Welcome, glad you're here. I was like that too, nothing "tragic" happened, except that I knew my life was about to collapse. Someone told me it takes a lot of courage to quit of your own volition before tragedy strikes and forces the issue. It sounds like you have pain in your past, and many of us can relate to that and to the importance of dealing with it. It's a journey, and we're all figuring it out as we go along. We're in it together...and the
something that will tell you it's worth it are the people here.
