How should I stop feeling like this?

So I’m 22M and I’ve always been an avg person like I’m always mid at everything. I was fat and not good looking during my school but did much work to remain atleast a known person to everyone in the school (that time considered many people as friends but later came to know they were only present to get any help), so never had any gf or even a close female friend. So right now I’ve some friends like everyone either has gf or a close female friend and they talk about them everytime I’ve a convo with them. They even have more better friends and good social life than me. I’ve lost weight and changed my appearance on a visible level. Even received praises but just for a month. I thought this might be a good chance to become friends with everyone and maybe more closer friend to existing friends. But failed terribly. Even my college life was worst, I just had to appear for exams and I’m from Tier 3 town so wasn’t able to make much new friends. So the main problem with me is that whenever I meet with my friends all of them talk about them at a point , although they don’t flex about it or something in front of me neither I’m jealous of them but I really feel bad and feel hurt at that time cause I ain’t that bad kind of human and Mannn when I open insta , it gets more worse. Like I literally feels numb and sometimes cry at night. I’ve tried my best to keep me busy all the day but at night when I’m about to sleep this things always comes in my mind and bothers me and make me ask myself “Am I that bad?” What should I really do?
