This is just my personal observation and opinion. I am not a doctor or psychologist. However I think many members here know I'm a recovering alcoholic, and I worked in a residential treatment facility for five years.
That long rant (it is always a long rant, never a short one) sounds very much like many of the patients I worked with (and myself 17 years ago). It is very typical to blame addiction on some one else: it is always some parent/sibling/friend/lover/boss etc that "makes me" drink or do drugs.
No, those people are not making you do anything. The first step is recognizing that your life is out of control, and your problems are of your own making. Progress can only happen when you are willing to engage the idea that you were present when all this stuff happened to you.
Lloyd you may not be an addict now, or perhaps you already are. I don't know. But I've traveled down the road you are on, it does not go anywhere you want to be.
