I had to believe in my recovery method. It had to make sense to me, and most of them didn't. As soon as I learned about my AV, I understood that was the way to fix my faulty thinking. It might not be right for everyone, but it was right for me, and I'd already shopped around.
The hardest part was believing in myself, after everything I'd been through and all the things I'd done to myself. That's where I credit SR.
I think belief is HUGE. The smallest change of perspective can lead to the epiphany that finally breaks that old faulty wiring in the brain.
It all starts in the mind.
