Welcome to sr, wonder! You can do this. Honest, open, willing... That's one thing that helped me quit drinking. Honest about my problem and my feelings, open to try just about anything to stay sober even if it meant going outside my comfort zone. And willing to do whatever work it may take.
You don't need to go back to who you were. A new, sober man who doesn't have to drink OR overeat to deal with life is inside you. You can uncover him.
