You aren't alone on this one. I've just about lost all hope in humanity myself. Because I'm outgoing, I've always had people that wanted to be around me but, after they get to know me better they decide I need to change who I am. As a result I end up more hurt than if I never opened up in the first place. It's hard to guard who you are from people and make friends though. I'm 30 now and I just found a true friend. Keep being you!
