Hi. Does anyone have experience with this diagnosis? I have read a bit online, but thought I would get info from those who have dealt with it. My difficult child, age 17, seems to think that is what he has. I am not certain why he feels that way (other than that he is very smart and likes to do his "research", almost to a fault, where I think he reads about something, and then makes himself "fit" the diagnosis). His current therapist feels that he really fits the bipolar description, and we have heard that from other therapists in the past as well. I don't know much about Borderline (BPD), so if any of you can give me some idea of what it "looks like" in your family members, that would be helpful. Thank you.
