well, do you really consider it to be 6 years, considering your recent relationship with your ex? For me, the healing wouldn't have been able to begin until after the intimate relationship ended.
I don't know - do you want to tell us more about how you're feeling or the circumstances? It's probably too easy for us to draw assumptions or to give suggestions that don't apply to your situation, since we don't know much.
But once again, my heart goes out to you, because I know that it can't be easy. But, it DOES get better...
