Hi Sober,
I know the crushing anxiety you feel. I became a daily drinker because I couldn't stand the next day panic, so it was a matter of postponing the inevitable suffering. A few shots here, a beer there...just enough to hold off those terrible thoughts. Eventually, I would end up with no money to buy booze so I was forced to just spend a day or two holed up inside until I was normal. Of course, now I realize that I was going through alcohol withdrawals that were potentially dangerous. The physical symptoms were bad, but it was the psychological ones that I really couldn't handle.
You have to break the cycle eventually and it won't be easy, but the pain is temporary. Seek some medical advice and get sober!
