I've made a noob mistake after noob mistake and now I'm in this situation. I'm above the bedrock, in the Nether. I have only a full suit of enchanted diamond armor and 39 cooked fish. My health bar is at 2 hearts and my food bar is totally empty. I, for some reason, am not starving to death which I though I should if I jumped around enough. That depleted my food bar quickly but my HP is going nowhere. There is only one thing up here with me. The pillar of netherrack that I tried to jump off of. It didn't do the trick and now I can't get back up on it. I bashed out a few of the blocks before realizing that netherrack doesn't drop itself if you don't have a proper tool, and only your fist.
What should I do to kill myself? I know this might sound like a crafted puzzle. Indeed it is a bit of a puzzle, but I also really am in this situation. :-\
Sadly none of this will work. I don't have cheats, I used up my blocks like a moron, and I have no bow and arrow on me. I current have a friend who is very new to the game and has no experience coming to try to bring me a ender chest using supplies he's going to grab from my mansion. Hopefully he'll succeed. Otherwise I guess I'll request for the admin to /kill me.
The easiest way is, putting a minecart on a rail underneath the highest bedrock you can find, jumping in it, and throwing a few enderpearls whilst trying to get out. You take a little suffocation damage.
But because people can also glitch up there, a lot of servers leave a hole at 0,0. (Which can be done in survival mode; doesn't need cheating)
Yea, I know a few ways of doing it. The OP said his friend is inexperienced, so I was just wondering how he was going to get his friend up there.
And if someone on the server has the dragon egg, it's quite simple to break bedrock.
I don't have the ability to use cheats or spawn or edit nbt data in the server. What I ended up doing was to get a friend to come up and rescue me. He failed to throw an ender pearl fast enough, so he suffocated in the bedrock. But he dropped the four pieces of dirt that he brought with him above the bedrock and I was able to kill myself with it. I guess as a puzzle, this one I created might be unsolvable. But from my perspective, the issue is resolved.
Just throwing enderpearls up doesn't work any more, in 1.12, unless you happen to glitch.
You have to get into a minecart, then jump and throw a pearl.
(Or there's a couple of more obscure ways)
Actually, ender pearls still work if you know how. You need to find a 1 wide x 1 tall x 2 deep area at the top bedrock layer to throw the ender pearl into. If you can't find an area of bedrock like that, you can place your own solid blocks to make it. Toss an ender pearl to the back and you'll spawn there with your head in the top bedrock layer, then you jump and toss another pearl.

It does if you're in the right place. That's how I got up there the first few times. I also added a mine cart, which is what my friend used. But that's not really the point of the thread. I was already up there and new ways to get up there. The question was how to get down again.
I've heard about being able to get there, but never tried it. I understand enough you have to glitch yourself up there (via various means) but I have a few Q's as we're here ...
1) Reading this thread suggests the only way back alive is via a Nether portal? Does this connect you with an overworld/create an overworld portal?
2) Is it a featureless plain of bedrock? No mob spawns?
3) How high can you go? Do you kinda reach the underside of the bedrock of the overworld if you go high enough?
You said you couldn't reach the high netherrack you left, but you can.
Use the nether rack you have to pillar up next to the other pillar, then break the parts you can reach up to.
Then collect that netherrack, and pillar up higher to reach the next higher part.
You may have to chop your pillar down to get blocks that fell to the ground, but with some patience you can get back all your nether rack.
Then put all your armor in a chest (if you have one) or take it off, and pillar up high and jump.
He covered that in the OP: netherrack doesn't drop as an item unless you break it with a pickaxe. If you just use your fists, like he had to, or any other item or tool that isn't a pickaxe, it just disappears.

You can also use the ender dragon egg to break bedrock and make an opening to get back down.
And yes, you can do that in vanilla survival. No cheats or mods required.
An overworld portal will never connect to a nether portal that is above 128.
Correction, an overworld portal will never connect to a nether portal whose base is at Y128+. Drop the base down a block and you have a portal that will link from the overworld and allow you to step out above the nether roof.
Portal on the left will not connect from the overworld. Portal on the right will, and then you just hop up 1 block to get out.

Ah. My bad. I missed that. I just never go anywhere without enough wood to make a crafting bench and enough iron to make new picks, so I assumed...

Cheers, CM. Getting to the Nether roof was always something I thought about trying, but when I read Herb's reply about not being able to form a regular "gateway" as such i.e having to always glitch to get up there, I kinda decided not to. But the lowered portal or the dragon egg punching a hole in the bedrock idea makes me interested again!
Yea, I was wondering about how he ended up above the nether with nothing but food myself. Too bad he didn't share the story.
Here's the full story. It's a pretty funny one, if you enjoy laughing at me, which I do. I've been playing for only a couple of months, so I'm pretty noob in some ways.
Motivation:
I found a village really far away from my home on an Elytra flight to find a Woodland Mansion to raid. In that village was a librarian that sells a Mending book for 16 emeralds. A pretty amazing find. I wanted to create a way to get there from my home reasonably fast so traveling through the nether sounded like a good idea. I wanted to explore above the bedrock because I'd never tried that and it sounds like by far the easiest place to travel long distances due to the lack of obstacles.
The process:
I made a ladder up to the nether roof and I began reading and watching tutorials. I tried ender pearls without the minecart, that worked unreliably, I tried chorus fruit. Many things I tried were outdated and fixed so they had no change of working. Occasionally I just died by suffocation in the bedrock. So generally when I do things like this that are dangerous, I drop all my stuff off in a chest so I don't lose it. I got up to the nether roof several times, actually. Every time trying different things like building trees to break bedrock, etc. I occasionally died accidentally or killed myself. Many times running to retrieve my drops so I didn't lose stuff.
The problem:
I always travel with an ender chest and a silk touch pick axe. But I had done this so many times I was losing track of what I needed to do and I got sloppy. Constantly going above and bellow the nether and sometimes dying became repetitive. I placed my ender chest under the roof so I could grab some rail and cart to make the final way up. I ditched all my valuables and I was so eager to see if the minecart trick would be as easy as I'd hoped that I forgot to pick up the ender chest again. Uh oh.
I ended up on top with just a few blocks. No ender chest like I needed, which would have allowed me to build almost anything, like a portal to get back out or chorus fruit to get under the roof. So I go frustrated that I new I was going to have to die, go back to my bed, and walk all the way back. So I quickly blocked up and jumped. I thought that 10 or so blocks would kill me. I was low. But I forgot I'd left my armor on and I have full enchanted gear, protection IV on everything. Feather falling IV on my boots. I didn't die. I figured I'd just break the pillar and do it again and then the realization that I might be stuck up there struck me. Netherrack doesn't drop if you just punch it. Uh oh.
A failed attempt at suicide:
I've never starved to death. All this time I figured it was because I'd always eaten enough. Little did I know it was just plain old impossible. My server is not on hard mode. I put a C battery on top of my W, Control, and Space key and sent myself of sprint jump running across the bedrock and went to lunch. I figured an hour of two of that would kill me. Nope. Then I went to this forum for some help. If you've read the whole thing you'll know that this puzzle is probably unsolvable. So I never did get a good answer.
The solution:
Lucky for me, everyone on the server are friends of mine. One of my closest friends and the one who was free that day for an hour to help me is by far the most noob on the server. I talked him into playing Minecraft with us only a week before this happened and he had only played two sessions so far. He was the proud owner of a cube house with one furnace, crafting table, bed, and a tiny farm four chickens. He's not capable of silk touch picking up an ender chest or getting the blaze rods or ender pearls to craft them. I also couldn't give him any of mine because I keep most of that stuff in my shulker boxes in my ender chest.
But he was willing to come up on a suicide mission to aid in my own suicide. I told him he just needed to bring me few blocks. I instructed him on how to get to the nearest nether portal, watched as he got the advancement for going to the nether, explained where there ladder was and how to get into the mine cart and stand up and jump. He did all of this and died of suffocation, dropping 5 glorious blocks of dirt just above the bedrock right at my feet. He died, I killed myself, and then I ran back to the scene to pick up my armor and place an ender chest and a portal on the nether roof this time.
Cheers, CM. Getting to the Nether roof was always something I thought about trying, but when I read Herb's reply about not being able to form a regular "gateway" as such i.e having to always glitch to get up there, I kinda decided not to. But the lowered portal or the dragon egg punching a hole in the bedrock idea makes me interested again!
In my older world I glitched up with an ender pearl then used the dragon egg to break a block of bedrock near my nether hub. Now I have a ladder leading up to that hole and the top of the nether.
I placed a beacon nearby, and a glowstone block directly above the ladder so it's easy to find from a distance.
I had planned on doing some things up there, but haven't done much yet.
How to break bedrock with the dragon egg:
The dragon egg has an unusual property. If it falls on another block in a lazy chunk, it replaces that block, even if it's bedrock! Lazy chunks are chunks at the edge your render distance, on the border of the unloaded chunks. In lazy chunks redstone is still processed, but entities are not.
So how do you drop the dragon egg in a lazy chunk? The easiest way is to use a lazy chunk machine, which is a machine that activates when it enters a lazy chunk. The machine I use looks like this:
You will need 2 redstone torches, 2 repeaters, 5 redstone dust, 1 sand, 2 normal and 1 sticky piston and some building blocks. Add an inverter and a piston to the output (1 more redstone torch and piston, oh, and the dragon egg) and you are ready to break bedrock.
To activate the machine, place the sand against the sticky piston and it will start bouncing back and forth between the pistons. Now just back away until you can no longer see the machine, then go a bit further just to be sure. When the machine enters a lazy chunk the sand will drop and activate the redstone output in front of the machine, which will turn off the redstone torch, retract the piston, and drop the dragon egg.
Note: In SSP you can reduce your render distance to 2 so you don't have to go far (but it's not necessary).
If you are breaking bedrock around an end gateway portal, you'll want to build a platform under the end gateway to catch the egg before it falls into the void, or duplicate the dragon egg before you try this.
If you want to break more than one bedrock at a time you can duplicate dragon eggs with the end portal, then set a line on top of slime blocks and drop them all at once with the lazy chunk machine. That way you can break rows of bedrock instead of just one block at a time.
How to easily duplicate the dragon egg:
You'll need to remove the lava pool under your stronghold end portal and add a fencepost under the back-center portal block (well I suppose you don't have to remove the lava, but it makes it easier).
I did this with a couple of cobblestone walls attached to the back of the portal frame, but you could just stack two up from the floor, and any kind of fencepost should work.
Next you'll need to dig up into the ceiling a bit because you'll need to drop the egg from six blocks above the portal, directly over the fencepost.
I add a stair and slab above the portal frame to make it easier to reach.
Obviously the portal needs to be active for this to work, and when you drop the egg and then hop through the portal you will find a loose egg entity you can pick up, and another egg placed in the center of the obsidian platform. You'll need a piston to push the placed egg so that you can pick it up, and then you'll have TWO dragon eggs! Need more? Return to the overworld and drop both dragon eggs through portal in the same way, and when you hop through you will find 3 loose egg entities to pick up and a fourth placed egg (repeat as many times as you like, doubling your egg count each time).
Here's what it looks like in my survival world.
I just place the falling block I want to duplicate against the Jack-O'Lantern (which is 6 blocks above the portal) and let it drop. Note that this can duplicate any block affected by gravity, sand, gravel, anvils, and of course, the dragon egg.
I've made a noob mistake after noob mistake and now I'm in this situation. I'm above the bedrock, in the Nether. I have only a full suit of enchanted diamond armor and 39 cooked fish.

If you'd like to talk with me about other games, here are a few I play.
Team Fortress 2
Borderlands series (Borderlands 2 is my favorite game, ever. TPS combat is a lot of fun and makes up for the lower-quality story, in my opinion)
Elder Scrolls series
Warframe (IGN is something like That_One_Flesh_Atronach)
Pokémon series (HGSS forever)
Rocket League
Fallout series
Left 4 Dead 2 (Boomer files always corrupt though)
SUPERHOT (SUPERHOT is the most innovative shooter I've played in years!)
Dead Rising series (Dead Rising 2 is one of my favorite games, and the 3rd was a lot of fun. 1st has poor survivor AI and the 4th is bad)
Just Cause series
Come to think of it, I mainly play fighting-based games.
This seems like your only option to actually die.
However, getting 10 obsidian to make a nether portal, and a flint and steel to light it seems like a better option.
How is your friend going to get up above the nether roof with you?
He's on a server already, so no LAN option available.
And just out of curiosity, how did you end up n this predicament? That's gotta be a good story...
Must have missed that somehow.
If you're on a server, ask somebody to teleport to the roof via ender pearls. Then they can just build a nether portal and you can escape.
