I've been there, counting the minutes until noon on a Sunday so that I could buy beer.
The good news is that you don't have to feel this way ever again. I'm sure there is a noon AA meeting somewhere near you, go to that and tell them that it's your first AA meeting. A lot of people will offer their help. You should also see a Dr. for medical help with withdrawal. You could try the ER at a local hospital, or a walk in "prompt care clinic." You can get through this, but you need to take active steps to do so.
