My friends are really getting me down.. help?

Fair-weather friends aren't friends at all. If they aren't being good friends back to you, don't be mean to them, just find people who will. You are not married to your friends, and by that I mean you aren't really committed to them. If they aren't good friends to you, then don't waste time with them. Life is short, find friends that make you happy and that you make happy.
