Why is it so hard to make friends?

I wish sometimes I could be more mature for my age and try to fit into the standards of what university students should like and behave. But I genuinely don’t find myself interested enough to the big things that people my age like. I feel a part of myself it’s because I’m neurodivergent/ physically disabled and I love childish things and besides the fact I have a lot of struggles with communicating verbally and trying to express my feelings,and it’s so hard to find friends that have the share the same interests as me, because most of the people like to go to parties and do stuff that I just really don’t feel comfortable doing/ can’t do because of my disability . And genuinely it’s so hard finding friends that have the same interests as me and it’s just so hard finding friends who will accept it and actually enjoy the same interests as me. I just really wonder why im so different from the others. I mean im kinda used to being alone without friends but I just sometimes wish I could experience what friends do yk?
