So I was entering a nether fortress because I needed to craft some eye of enders, but the problem was, I forgot to bring golden armor, since my fortress was next to a crimson forest, so I needed to head back to my portal to get my boots so that the Piglins wouldn't get hostile.
On my way, I decided to kill some blazes, I accidentally hit a Zombified Piglin, and I had double trouble. I was cornered and had to get out, so I mined the nether bricks and almost fell in lava.
I didn't realize that the other side of the fortress was soul sand valley, and the ghosts started spamming fireballs at my face, and I didn't bring any potions with me. I decided to run, not realizing a hole that would lead to my death, I fell in a large lava pool, and started to take damage.
I screamed as I burned, and I had 1/2 of my life left. I found some striders, and I remembered I tried to ride one before going to the fortress, so I quickly saddled on one and had warped fungus on a stick. I started to eat my bread and I survived that danger.
An hour later, I finally found a stronghold, although I didn't have enough supplies to fight right then, so this is my story. I may have beaten a couple withers, but the nether is more terrifying than that.
