Welcome Buffalo! This is a great forum for support. I get it here daily by reading what others post and posting my own struggles and experiences.
I have depression and anxiety issues, but I have not experienced the anxiety at your level. I know there are many people on this site that have though. So stick around and keep posting and reading.
I was prescribed xanax before and I wholeheartedly abused it. It is not fun to stop. I took it on and off for a year or so. You may know that it can be very, very dangerous to stop suddenly. Definately talk to your doctor about that.
The drinking I can certainly relate to. I drank way too much for almost 25 years and it takes it's toll on your mind, spirit, and body. I drank to fit in and be more socialble at first, but in the end I thought I had to drink to merely survive. It's a horrible place to be.
Don't be a stranger and talk to your doc about those xanax and your drinking. You have to be completely honest for them to help you safely.
God bless.
