How to get over being badly hurt in the past?

I have been used and abused by the last 3 guys I've cared about. I know, I have awful taste in men. that much is obvious... But these guys are now forever out of my life and I'm looking to start anew and find good sweet guys. But... I still have a lot of emotional pain and baggage from these past guys and I'm wondering, is time the only thing that's going to help me feel better?
