Welcome to SR nimeton
I am surprised your doc told you you were an alcoholic. Was this prompted by you or are there some health concerns?
I think the mental and physical side of addiction are so intertwined as to be indistinguishable. And just because you believe the problem to be mental doesn't mean it isn't a problem. Saying that even non alcoholic drinkers could benefit from a better mental attitude towards alcohol.
If you are feeling deprived because you are not drinking you could do worse than read Allan Carr's book on alcohol. It helps reprogram your brain a bit. Otherwise you'll find lots of helpful advice here x
