Have you seen a doctor for your depression/anxiety issues? I'm on day 9 of sobriety and I have an appointment on Tuesday to talk to my doc about getting some anxiety meds. I totally understand your weight gain issue as well. I put on nearly 100 lbs in one year. That was the year I had a breakdown. Maybe your doctor could help you prevent going through what I went through.
My daughter has autism, and my husband is frequently deployed because of the military. I developed a drinking problem because I thought it helped me deal with the stress. But I've found that drinking brought me a lot *more* stress than not.
Best of luck to you!
