It's like half the people you know never grow up, isn't it?
I don't know if your problem is about friends, maybe it's something else... But if it is, then know that even though there are a lot of a-holes around, there are good people out there... You just need to be open to meeting them and accepting new people in your life. Eventually the dxxxheads will trip up on their own immature dxxx-moves anyway.
I hope things get better for you :)
