I slipped last week as well. I also did it because of the pressures of home life and some other things. It is hard to deal for us right now and easy to drink. I, in particular, always hid behind a bottle. Now I have no place to hide and it is terrible. I'm having a terrible time coping. You may be as well?
I am not angry at myself nor should you be. As was said earlier, nobody can take away what you have done nor what you have learned. You slipped, that is all. Just keep trying and eventually we will get it right.
