conflicts have become usual part of my life and i hate it

ever since i joined my college. one thing has been common which is conflicts in my life. from friends to relationship, all things are falling apart. I'm beginning to think I'm the root cause of the issue. i don't like my college. it's a tier 3 college. lectures are boring. i don't find classes interesting. a person whom i befriended in first sem left me saying I'm irritating. later in third sem, my one friend said, " bhai apni image change kar, class ke baki log bolte ki mai tere sath kyu baith ta hu" i was surprised since I don't much to those guys. i accept that I've myself done mistakes like i told my one friend I'm autistic during first sem because i thought people who don't talk much are autistic. his group thought I'm weirdo. later i realised i meed to befriend people so i don't remain loner. all these things make me self conscious and anxious.i just want peace in my life at this point
