Your Dr might have been half right, you know. The part that was correct was the part 'Just stop drinking and you'll be fine', and that is the part that really matters.
So, we know what you are going to do, the question is how are you going to do it? Make is as safe and easy as possible is my suggestion, and that starts with seeing a Dr, maybe a different one. Instead of asking what is wrong (you already know the answer to that one), tell him that you are going to stop drinking and you would like his help. Take it from there.
