Can't get over my ex 'boyfriend'?

We were together for nearly 2 years, but we were not in fact boyfriend/girlfriend. He never called me his girlfriend, but everyone else, his friends and family regarded us as a couple. Being in a committed relationship with him was my fondest wish, and there is nothing I wouldn't do for him, but he didn't want that. Anyway, we broke up 6 months ago, and I was heartbroken. We're still friends though. I got severely depressed and still am 6 months later. I tried to start seeing someone else, but it doesn't help. I got even more depressed. It feels like my life is over, and I lost all motivation to do anything at all. Is there any hope for me to ever have any sort of happiness in my life?
