I've had mental health diagnoses for years. A.D.D., depression, anxiety, and PTSD. This year, I was diagnosed with a "mild case" of BPD. Finding this out, I told my mother of this diagnosis. She claims to want to know how to better talk with me. I've given her articles and book suggestions on relationships with family members who have BPD. 
She has never looked at any of them. Instead she gets upset with me. She gets mad that I shut down whenever she tries to have a heart to heart with me. Because whenever we do have a deep conversation, instead of trying to understand my feelings, she tells me it's my problem and I need to learn to see the positivity in life.
I've been working with a therapist since my diagnosis. She has been trying to help me acknowledge that my mother doesn't seem like she will ever learn how to validate my feelings and it won't ever be a truly healthy relationship.
Has anyone else had a similar situation? I don't know how to effectively communicate with my mother and explain how to better understand me. I don't know how to explain any of this to my mother without her putting me down about me being "too sensitive."
