I’ve been experiencing extreme episodes of rage when I feel attacked, rejected, or misheard by my partner. These episodes seem to be very similar to what I read about BPD. I do believe I carry a sense of fear surrounding abandonment with my partner but I don’t know if it came before or after the rages started. Either way it looked like this last time comment made - feeling of rejection - fear- rage - leave screaming before I can be left. 

I only have these episodes with her. I can count on one hand the times I raised my voice before this relationship and have otherwise been exceptionally peaceful. Is it possible I’ve had BPD that is only triggered by a partner? I do relate to the symptoms but I also have bipolar disorder and adhd which overlap. Thank you
