I was diagnosed bp2 but currently I am questioning my diagnosis as well. I don't think I have mood swings, but more mood shifts or switches. I go from being level, to hypo, to anxious, then irritable in like the span of like an hour. But my biggest issue right now is abandonment stuff. Bpd and bp2 definitely share similar symptom traits. Good luck, I hope you find the answers you are looking for.
