Ran into an issue involving lava [closed]

I used a fire resistance potion to get under an ocean of lava, but forgot that I left my second one at home, so how do I escape? My picks are too low durability, and I don't have any wood.

And, it was in the nether with about 200 blocks to shore if I could swim in lava.

EDIT: Never mind, an admin is fixing it.

Lava oceans don't cover the entire floor of the Nether, some parts are netherrack. So you could dig to the sides and occasionally dig up, quickly blocking it off again if lava flows in.

Even if you have ender pearls, throwing one through the lava ocean and hoping to hit land won't work. Lava slows down ender pearls, so it would only land at the bottom again.

And if nothing helps, you can make a safe space under the lava ocean, blocked off from all sides, remember (or screenshot) your coordinates using the F3/debug screen, drop all your items into the safe space, close it off from the outside and take a refreshing bath in the lava. After your death, you take a fire resistance potion and a pickaxe, swim down there with fire resistance, make another safe space (so that lava doesn't flow to your items), then open the space with the items in it again and collect them.
This way you'll still lose a bit of in-game experience, but maybe you gained some real-life Minecraft experience from this situation. ;)
