Your progress will depend on three essential ingredients: Honesty, open-mindedness, and willingness.
Understandably, the prospect of knowing yourself and being known for who you really are is frightening, and so it inspires a great deal of fear. The key is using honesty to see ourselves in the mirror. Then, you will need to be willing to accept genuine expressions of staff and peers of how you present yourself, and open-minded of their assessment both in your strengths and weaknesses.
Your community is your ally. Your reassurance lies in the fact that all of your peers have the same basic problems and they too are seeking freedom from addiction. Therefore, they are both deeply understanding and supportive of your efforts to find your way to freedom and discover the real you.
The more structure and support you have the better chance you have of remaining clean and sober.
