Help, I'm way too anxious?

I'm in uni, before last semester I made a post similar to this one about being nervous of going back to normal classes because I just feel being around so much is too much for me and although I force myself to do what I want (socialize every day, get out of my comfort zone) and get good grades, it's just always difficult for some reason, I was told maybe it was because of quarantine, but I know it's me. The semester went well, I have amazing teachers, great classmates, good friends, and the people there are nice, but I have a terrible time adapting, it's actually like I never finish adapting, I just keep pushing myself to be there till I don't have to be there and then the cycle repeats again. There are days when I don't want to talk or socialize in any way, in vacations I can simply spend most of the day in my bedroom for like a whole week (or more) without saying a word (just saying hi to my parents and maybe a small talk) and after that I'm fine again, but that's not possible during class and I finish feeling like I'm about to ugvhbijnho. I'm already nervous about going back to class and I feel like throwing up, I like to have control of myself and I'm strict with myself, but I just haven't been able to totally control this about me.
