i realized my freinds were all actually fake, and that they were talking bad about me and putting in a bad grade even though i did contribute in things. now that ive left/ignored them completely, i dont really have any freinds to talk to or hang out with. i dont even know why they hate me, and i dont know if i should talk to them again or just make new freinds outside if class while ignoring them. even people are embarrassed to talk to me around my group to not tarnish their reputation. they say they are fine with me, but the secret animosity and passive agressive comments are very obvious. i overthink alot and it ruins my health both mentally and physically. what should i do?
