When I decided to get sober I thought all my problems would go away. Then I realized that I was using drugs/alcohol to silence my problems and they were all still there staring me in the face. The difference is now that I'm sober I can start dealing with these unhappy feelings and emotions in a rational manner. My problems will never completely go away because problems are part of who I am. Being human I'm not designed to feel perfect 100% of the time. I'm learning to live with that. It's a slow process.
Hang in there. Don't give up!
