I have anxiety, but I actually prefer to be by myself. I do have friends in lessons, but most of my closest friends stayed at my secondary school (I'm in sixth form college by the way). I realised that I tend to befriend people who are the complete opposite to me, and I haven't found anyone who has the same interests as me and who has the same hobbies. I used to be a social butterfly and tried to talk with everyone, but over the years I just started going around with a b**** face and a "I don't give a ****" attitude, which is probably why people are scared of me and do not approach me lol. But at times I do feel lonely and wish I had someone to at least eat lunch with. I sort of understand you, and advise that you go seek professional help so that that loneliness will not effect your grades😊
