I've always believed that I could heal myself
I'm a smart guy, I used to think the same thing.
After many attempts to get and stay sober over the years, I realized a couple of things.
1. I was a drunk.
2. I was using my own logic and thinking to get, and stay, sober.
Conclusion #1. I was relying on a drunks advice and experience (my own) to get, and stay, sober.
Conclusion #2. Maybe I'm not as smart as I think, and I should get some outside help.
