Ana....I see your updates and I have to post this.....STOP.
If you are truly looking to get sober then stop dwelling on the bartender's failure to see you were intoxicated, seeing if the bar will ban you, not showing up to work because you got drunk?
Seriously, get to rehab, a doctor, AA, counseling, SMART.....etc.
Your thinking is highly unhealthy and we will be here to help you along the way but no one is to blame for last night except you. Once you accept this then you can move forward.
I hope you get to a better place and I mean that my friend.
