felt like I had died? (trigger warning)

No other idea where to put this, but it seemed most logical. If not, I'm sorry. >.> This happened to me a few days ago, and on another forum I was on I got suggestions of some kind of psychosis and depersonalization (which seemed more correct). I have an issue with dissociation but I won't be able to see my new T until the 19th; it's only my 2nd appt. I'll ask when I go. I'm pretty much copy-pasting so it's going to sound very messy because it was posted the same day it happened. All I really wanna know is if this in the right forum and if not, where should I put this to get more feedback? If it is correct, any idea why it would happen? And so suddenly/randomly?

TRIGGER WARNING AHEAD


From about 5pm-7:30pm I was depressed and unmotivated to do anything. All I wanted to do is put my head down and just lay there. It got worse and worse and it felt like light-headedness but without being light-headed. It’s hard to explain. Around 7:30, I ended up getting extremely anxious, and I mean “I feel like I’m going freaking crazy” anxious. I was with my boyfriend so he noticed and asked what’s wrong. I felt like I was on the verge of either a panic attack or dissociating the entire time but nothing happened. I sat on edge for nearly an hour. I told him I felt like I had died and gone to hell or something, which is weird considering I’m atheist but I might have just had no other way to explain it. I had seriously thought I died, though, just out of the blue for no reason. I have no idea why I so suddenly felt like I was going insane. He tried to help calm me down but it didn’t really work. I felt so terrible. I had to curl up into a ball and was scratching my legs and biting my arm. The mark on my arm was there for hours. I was twitchy and kind of scared but it slowly (during a period of about 30-45min) it went away. I was fine literally right after that; it stopped dead in its tracks and I was back to normal. Nothing had happened that should have made me felt that way. No triggers, no bad experiences, had a decent day, zilch.
