Embrace the depression, feel it, acknowledge it. Face the fear and feel it. After a while it becomes like one of those bad dreams that scared you, but then you knew what was coming and it had no effect on you. Drinking is only going to cocoon you, and eventually repeat this cycle and this process. I would def go see a doc, if you think you may have any other physiological/emotional problems or any other valid mental issues. Eat a healthy diet, shower daily, exercise, read, do not smoke or use any other mind altering drug, if you have a doggie hug him. Get outside and say prayer to your higher power to help you. This is not going to be easy.This is your spiritual lesson, that's all. I can't stress that enough. Alcoholics get a gift, in the form of this life lesson, that other never get the chance to experience. Treat it like a test you know you are going to ace, and you will. It is a badge of honor to you soul to stay sober.
