Yes indeed AMD Junkie, this person hit the nail on the head. If I had been told this a few months ago, that I am very opinionated, intolerant etc., I'd have said, "Yeah, so what?" I'd never have tied that together with being the "cause" of this predicament. Either way, I wouldn't disagree with the statement.
So far, I've caught myself being very "judgmental" several times since I posted this. Ordinarily, I'd consider that normal and carry on. But the step that usually follows being judgmental is being pissed off about it to some degree. So, when I caught myself with those thoughts, I just let it go. Consequently, I haven't been pissed off lately at all! Now, that's a revelation!
Thanks for your help, input, and good wishes. I have a feeling, by the time I get to the therapist, he won't have too much work to do after all.
