Addictive Personality

I don't want this to be an excuse for me, but I've always had an addictive personality.
I started drinking heavily when I was 11 or 12.
I started smoking cigarettes when I was 11 or 12.
I started self harm when I was 12 or 13.
I started sleeping around when I was 12 or so, mostly selling myself for booze or smokes. 
I would use inhalants like paint thinners and stuff like that (I know, usual teenager crap, but I've always avoided the hard drugs), but I haven't done that in a while. 
I fell into binge eating for a while.
If I don't have one thing, I have another, or I find something new.
It's almost like it's what brings me structure in life.
