I learned that there is nothing for me to be ashamed of. I am an alcoholic, I have brown hair, I have PTSD, and I have blue eyes nothing there for me to be ashamed of. Being an alcoholic does not make me a bad person. Yes, I have done some things that I could be ashamed of while I was drinking but I have learned to separate the act from the person.
Yes, many times in society people will judge others because they have a mental health issue or an alcoholic. What others think of me is really not my problem or my business. What is my business is how I treat others and myself today. Today when I make a mistake or harm someone I am quick to repair the damage done.
If you have not done a Fourth Step inventory and a Fifth Step I would strongly suggest it as it will relieve you of this feeling of shame if you are honest with it.
You are a worthwhile person. Don't give up yet, a new life is just around the corner waiting on you to go there.
