Hi...you sound as though you might be a "double winner"...one of us fortunate folks that have at least one alcoholic parent and all that that brings, on top our own nicely brewing illness.
I would guess that you're someone who strives to be independent, minimises your own problems and worries about other people a lot. I could of course be off base there.
None of that bars you from being an alcoholic. It just might make it a little harder for you to see the problem. If you have little control over the amount you take once you commenced to drink...or if when you honestly want to you cannot quit entirely...you are probably alcoholic. Least that's what our big book says.
You don't need to drink like your dad did. Neither do you have to have the same personality as he has. Alcoholism can play out in lots of different ways.
