Ive had a bi polar diagnosis for 12 years and have dealt with both predictabe moos swings and rapid cycling. I'm my mania I'm implusive, gregarious at one moment then pushing people away at the next. When I crash into depression I isolate, feel alone, desolate and like nobody wants me. I just got diagnosed with borderline personality disorder. I've read up on some of the characteristics and am trying to differentiate between the two and how they differ that greatly. Is BPD just a broader terminology or are it's traits so specific to it's own MH disorder much more severe?
