billgyrotech would have you believe that his personal difficulties, whatever they may be, are an excuse for his bad behaviour and this is evident from several of his replies. I know people who lost a spouse or son, and others who are going through cancer treatments. None of them were driven to act like a$$h013s due to their personal tragedy because it wasn't in their nature to begin with. That is the difference.
I'm no psychologist but have been involved with people (and their treatments) who have certain personality disorders and that's what I see here (a personality disorder). billgyrotech - I say this with all seriousness and some empathy - I'm fairly confident that there is a diagnosis and treatment for you. Maybe you should seek that out and it might become apparent to you that the whole world can't be wrong and that you are the common denominator in this equation. Then you might be more able to get positive results, not just here, but in your whole life.
Good luck.
