Kitten,
You fell into the trap of looking for an excuse. I did that a hundred times and trust me, if you look for an excuse to drink/use, you'll always find one!
I think we have felt the pain of being labelled as a drunk or whatever. I know how awful I feel whenever I hear people talking about alcoholics like they are some lowly life form. And, it happens too often. But, don't let it get you down.
Love, Anna
