Is it worthwhile?

I have seen similar posts but I am hoping for more advice.

My current situation is this: I was recently convicted of a felony for a 3rd DUI offense. I was a special eduation teacher and was fired from my job. I really don't know what else I would enjoy doing except nursing. I have looked into different programs in my area and would like to try.

I have made huge life changes. Since my arrest, I went to a pyschiatrist who was able to more accurately diagnose my depression and treat it more effectively. I have been treated for 10 years (since I was 19) and have had significant family trauma -- things no family should have to go through. I have been attending AA and have been sober for almost 9 months now.

I would like to know that there is a possibility for me to change my life and turn this horrible event into something very positive. I'm told that this will lead me to a better way and that I will overcome if I continue on my current path.

Does anyone have any insight or advice? I am so full of guilt and pain that I need hope to get me through. I love going to school and I have a Masters degree in Counseling and I think that nursing school would be a great opportunity for me to regain self-worth and contribute again.
