You should seek medical help for withdrawal. To quit drinking many people use a program of recovery because trying to do it by yourself doesn't usually work. Many people choose AA and it's what I currently use. I would recommend that you try a few meetings in your area and tell the folks you meet that you are a newcomer.
In my opinion, face to face support is very important and that's one of the things that AA provides. However SR provides a very good supplement to F-2-F and is available 24/7.
Welcome.
