This is EXACTLY what I would have wrote at 22. The first signs that I had a problem were my behaviours in relationships with men. I was a single parent, working full time, and going to school full time... Maintaining a great average. I didn't drink every day, in fact I could go quite a while without drinking. Sometimes, I could even stop at one.
Reading this gave me the chills because I knew it was a long the same lines of what I would have been writing at 22. I knew I had a problem then but never stopped. PLEASE STOP. I am now 30... and I have just lost everything. Don't be me... Don't wait until you lose your entire life to stop. Find any way you can to quit. ANY WAY. I know it won't be easy. You'll have a ton of temptations being in school, with a circle of friends that drink a ton... Please find a way.
I'd give anything to go back and change it all. I'd give anything that you don't do the same things I have.
