I'm in my first year of University and have been very happy for the last couple of months which is slightly unusual for me as I've never been entirely happy with my life. I assumed it's because I'm in a new city with new friends who I really get on with and don't have all of the worries I used to have. Anyway, suddenly I've started feeling terrible. I feel like a lot of my friends are out to get me lately and don't really like me, and have noticed that they don't really care if I'm around or not. I've been isolating myself lately for this reason and because I don't feel entirely comfortable around people anymore. I've lost my appetite which is strange as I usually don't stop eating and I have no energy for anything (just today I have left my bed only twice because I couldn't get the courage to and thus have been getting out of breath even when I sit/stand up). I've been feeling very nauseated although I haven't been able to throw up and I can't stop crying over nothing. I do have exams coming up however I haven't been feeling stressed about them at all as I've only got 2 although I know I will get stressed over them sooner or later. I'm genuinely just feeling extremely fragile and uncomfortable and find it hard to breathe, the fact that I live in halls makes the situation more difficult.
