I hear you. Sex addiction (if that's what you have) is not pretty.
I've seen a lot of people coming into SA and so far no one has said "things were going so well in my life and I thought SA could make it even better." No, people come in kicking and screaming, out of sheer desperation. With that as the beginning, things can get better. But we needed to hit bottom first. We needed that desperation. (Again, not saying you need SA, the same would probably apply to other groups, therapy etc).
Hitting bottom doesn't necessarily mean something really bad has happened. It means running out of other options. That's the only reason I joined SA, I'd tried everything else I could think of and nothing worked. If you think you have other options, try them and see how it goes. If you're honest with yourself you'll figure out what you need to do.
