Welcome, BPmom. Thanks for sharing some of your story with us. I've read that about a third of BPD sufferers also have bipolar disorder. I've also read that BPD is usually associated with abandonment or abuse in early childhood but, in a third of BPD cases, there was no abandonment or abuse -- which suggests that it to some degree is inherited. Having lived with a BPD ex and a bipolar foster son, I found that the bipolar swings normally are 4 or fewer per year, with the mood lasting several weeks. In contrast, BPD mood changes (i.e., rages and tempur tantrums) occur in a minute (sometimes a few second) and typically last 5 hours to 36 hours. As you must know by now, bipolar mood changes are gradual, being caused by body chemistry changes. BPD mood changes, however, are event triggered and thus occur nearly instantly.
