It sounds to me like you're in a pretty acute situation right now. You would not be the first person to go to the ER with a panic attack. You certainly wouldn't be the first person desperate NOT to drink, suffering with severe anxiety, to go to the ER for help.
There is no sense in white-knuckling it, when there is help available to you medically. I'm sorry, I just don't agree with that mentality at all. Whatever you CAN do to stay sober, is what you SHOULD do. You shouldn't suffer unnecessarily IMO.
Do you think you can go to the ER, find a detox, or be seen by another doctor asap?
PS- I detoxed in the hospital and it was by no means "easy", but I wouldn't have gotten through it alone.
