hey i've been there before with the alcohol and anxiety of regret. You end up with a uneasy stomach thinking of all the stuff you said that you can't take back and cant turn off the thoughts so the anxiety worsens until you find yourself purging. It sucks but what got me through it was taking a deep breath, a look in the mirror, and saying to myself "this hurts, I feel like I can't take it but let me try to get through this. things will be okay if I can tackle this problem and breathe."
try to see past it, a week, a month. Believe it or not there is a YOU on the other side of this,in the future who will not be burdened by that feeling so strongly depending on if you can put the bottle down. You can get there
