Please Help! Any ideas on how to start getting myself out of this horrible life situation?

I would suggest you see a doctor and get help for the stress, anxiety, depression and drinking. Also you diet is not very good. It does little good to eat only carbs, if you are drinking every night, and having shots during the day. I doubt if a daily plan will help you, because your anxiety is too severe for you to cope with alone. I would suggest you see a doctor, psychologist, or psychiatrist for help. There is no reason to have to live with these problems, but you must want to help yourself by seeking the type of help you need.
