>>84514 (OP)felt like this a while back, got over it eventually.
Leave any friend groups where you feel like the people are goy robots. Wasting your time with people you don't care about, that you know don't care about you, makes you feel hollow. If theres people that you enjoy spending time with, try to talk about things that you care about personally but you never showed in your fake persona.
Try to find new groups at school that you normally don't interact with, could be a club. When you meet these people, try not to hide your real self too much, and see if anybody actually likes that.
