Hello all
I’m a 20F diagnosed with bpd 2 years ago. I had a decent childhood but grew up in a cult and left when I was 13 but my teenage years were traumatic, filled with abuse, drugs and alcohol, suicide attempts, rehab, rape, abortions and homelessness. Bpd has RUINED my life. It has destroyed all of my relationships. I switch on my family daily and I feel drained 24/7 because of how intense my emotions and feelings are and how fast they change. I can’t even keep up. All that being said, my very toxic sister in law who told me she had no idea what bpd is and tried explaining her symptoms to me (none of which were bpd symptoms) told my mother in law this week she has it. My mother in law has watched me suffer over three years now and hasn’t tried to understand bpd or what I’m going through at all. Until my sister and law came out with this new info and now she’s “trying her best to understand it.” My sister in law has zero symptoms. She didn’t even know what it was!!!! I am so upset I may not be able to talk to my mother in law for a long time. I can’t help but feel it’s a cry for attention and a way to justify her actions (she went batshit this summer and tore the family apart). 
Idk what to do but I need some kind of advice because I am shaking. Am I in the wrong here? And if I am how do I feel better about this?
