Now I know. difficult child came by yesterday to visit her son and believe it or not we were able to talk. She was talking nonstop and every now and again I was able to ask questions that she answered and I believe honestly. Well, her diagnosis after a psychological test is Bipolar and borderline personality disorder. She said their are questions and she still needs to see the psychiatric. because of the bipolar diagnosis, she doesn't want to believe it. She thinks the only reason it's there is because she had been previously been diagnosis'd with it. I personally think this diagnosis is correct. She really doesn't seem to mind what her diagnosis is, the only thing she is adamant about is that she is not going to take medication. I believe her when she says that. She's had the borderline diagnosis in the past too, but maybe doesn't remember that and I had no input at all into this round of testing. I think the borderline diagnosis is very telling and definitely explains our tumultuous relationship for years! It's interesting, that I have felt that she has had this "personality" really her whole life and it's been difficult to deal with her. I'm seeing much the same Personality" with her son too, and what from what I've learned over the years, my difficult child's bio mother shows the same "characteristics". A few years ago when I studied up on borderline, pretty much the literature believed that abuse was the one thing that contributed to this happening. Last night when I looked it up again, they go ahead and also mention a genetic tendency or inheritability. I truly do believe this is what my difficult child has. My difficult child is in therapy. I hope she has someone VERY good to help her thru this and that my difficult child wants help for it. This explains sooooo much!
