Hey brother, congrats on getting sober, 22 days is solid. I just picked up 9 years in March. I don't know if you're using a 12 step program, but I learned in A.A that the way to truly build self esteem is to commit esteemable acts. When i started to be of service to those around me, I felt better about myself. It's hard to feel like a lowlife when people are smiling at you and saying thank you constantly. Once I felt better on the inside, my outside circumstances improved. I had confidence in regards to my career and my romantic/sex life because my emotional well being wasn't tied 100 percent to them anymore. I hope that makes sense. If you need any help with the sobriety portion, PM me. I got off heroin, pills, booze, and coke. Good luck!
