One the greatest gifts you can give yourself is the gift of peace. Many factors are involved in that quest. Your mind, body and spirit must be free and healthy. You have begun the process of healing your body but it sounds to me like your mind and spirit are still struggling. My heart goes out to you.
Since becoming sober I have take a hard long look at the people in my life. And I decided to make changes. TOUGH ones. I asked myself if I were to have met these people now would I invite them into my life. When the answer was no, then I walked away. It wasn't easy. I felt alone, I felt like a hypocrite, I felt guilty but those feelings passed. I have never felt more at peace in my life and it only keeps getting better.
A few of those people? My fiance (5 years). My mother. Various 15+ year friends. Did I feel lonely at times? Hell yes. But even during those times I was at peace. And I'll take peace over company any day of the week.
Best of luck.
