Dear Missy: How Do I Make New Friends?

I’m in third year now but i haven’t had any friends since second year. i talk to some girls in class but all my old friends have done stuff that i can’t really get past. i feel like i’m missing out on major life experiences like getting ready with people for discos because i don’t really talk to anyone.  i’m going into TY next year but i’m worried i still won’t be able to talk to people then. i don’t play sports so nobody in my year really knows ...
