I agree with the others here - you have to take it all one day at a time. Not only for sobriety, but for everything else, too. I was so easily overwhelmed in the first few weeks especially - I didn't get much done (except reading on this forum). BUT I was sober! Everything else, I figured was secondary.
Why not go to the doctor/psychiatrist on campus (most school have them) and tell them what's going on...... My daughter had to do that as she was suffering from major depression. They'll work with you......
Furthermore, you don't deserve to be punished anymore..... Alcoholism happens to all kinds of good people. Things really will turn around if you stay on track......:ghug3
