I’m anxious and really scared.

I’ve been around people a lot lately and been going out every weekend to watch theatre plays or go for lunch and I can’t help but now get into a loopehole into thinking that there’s no way I won’t fall ill and tu even though I don’t have a reason to believe that. I wash my hands and all that but still the sb just sneaks up on anyone these days and I can’t help but feel anxious as hell as a college student who has midterms coming up. I get hungry but always make sure I eat to a point where I only feel full for a little while and not for an adequate time. I can’t tell if I have cramps bc I’m on my monthly cycle or bc I ate something bad and that’s just making me not want to eat as much as I usually would like to eat to feel fully satiated. I’m really scared.
