It is one of the most common symptoms of BP and one that your therapist should not brush off as it is very dangerous. It is almost always one of the first 2-3 questions that a screener will ask you and is almost a dead give away in diagnosing. Those of us who are BPers will joke about it a lot, but it really in not a joke. The joking is just a way of coping and helping to keep ourselves under control.
