Did I(25m) just almost die?

First of sorry for paragraphic im on my phone. I wake up this morning around 8am with a terrible headache and I decided im gonna sleep a little more hopefully i will fix it. I wakw up around 11am with insane headache, back of the neck pain and nausea. I tried vomitinf but my stomach was empty so nothing came out. It was like a nightmare i couldnt stand still without being in pain/nausea so i went to bed after a hour of trying. I slept 3 hours again, i just woke up. Im completely fine and feel fresh as fuck. Its still surreal I was feeling like absolute shit and was thinking of going to the emergency care.

For context: Ussualy of Sundays im free and I sleep a little more. Headaches on Sunday are common but not on this scale. I thought the neck/headache pain was from my sleeping position (i sleep on my stomach with my head rotated). What do you think happens?
