Dot,
You go girl. Be yourself and if that means getting angry and cussin', well so be it. One time this pompous a** around here approached me and in that voice they use said "Laurie, you know, profanity does not equal recovery". My response to him was "F*** you". If that's what you need to do, then do it. I'd rather see you cus someone out and get angry than pick up that bag.
Love ya
Laurie D
