I think it takes years to diagnose bp2. Hard to believe pdoc was not offering more assistance though. I started getting symptoms of bp in early college and depression much earlier then that. I was not officially diagnosed with bp2 until my mid to late twenties. All the same I think self harming is more bpd then bp2. You could have both. I would start seeing a psychotherapist or a lcsw to start talking about your problems. That's been a life saver for me.
