Yes, what ubnt said about meeting with your boss. Go to work tomorrow and don't meet with your boss until next week when you have had some time to sober up and collect your thoughts. Chances are you will smell of alcohol and if you are like I was, still have alcohol in your system. I could just not stop drinking and would drag myself to work, reeking.
Your boss didn't do this to you, you did this to you. Just like I did it to me but I wanted to blame it all on everyone else. I think you know that by now and my heart is with you. I've been there.
Dump the booze. Go to bed. Do not under any circumstances venture out of the house to buy more if you have finished what you have in your home. Go to bed. You are not a bad person. You are not a horrible person. You can do this but I'm thinking you need more support in your life. Can you go to treatment?
