Sorry if the title is unclear. I’ve been recommended to post on this sub so here I go:

I (18m) have a diagnosed anxiety disorder and take pills for stress which I started takin after the first two incidents.  
The feeling I’m talking about is like if something infinitly big was inside my head, not something psysical but like a concept (and not that my body would be big). It’s like a thought I can’t control that is extremely overwhelming but can’t do much about except fill my mind by doing something else (ex: watching tiktok).

The first time I had it it was during a strong fever and it was something I felt when I closed my eyes (so not asleep). I thought about it alot since it was extremely strong to the point that I was almost disgusted by the thought. It stayed with me for 1 or 2 month: it would randomly flash for a second in my mind even without being sick, tired or anything: just random moments.

The second time I had it, it was just before waking up (pretty sure it’s what woke me up since). It then happened the exact same way exactly 1 week after that. The thing is that both times, it was an extremely stressful day for me since that day I had to give an oral presentation and had like 3 tests in school. So it seemed to be caused by a lot of stress. Before and after those events, I was very depressed and in general had an extremely dificult time actually going to class. Those 2 events happened at the end of last year and this year it’s been even worse. Obviously I’m very stressed by school and just going there is very hard. The thing is the feeling came back, the night of the day I started studying at home again. Before that I was basically doing nothing and I had to start studying at least a bit to go to tests and not have problems with the school.

So the first time with the feeling was during a fever but the 3 times after that it seemed related to stress.

I’m just seeking similar experiences and info about what it could be and even maybe other subs where it would be more appropriate to post this, thanks alot :)
