Not sure if this is the right flair, I apologize in advance. 

Been talking with my mom about my mental stuff a lot in order to better cope with it and get some sort of closure even though she's.. not a great person. But my mom has been invalidating all of my diagnoses and it's making me question myself. 

I've been diagnosed with BPD since I was 17 and was recently rediagnosed with it, comorbid ASPD as well as PTSD and persistent depressive disorder. She keeps saying it's not possible for me to be this broken, that I'm just dramatic and I have no reason to have any sort of mental illness (even though she went indepth when she talked about my trauma last night) etc etc. She says my therapist just wants me to be messed up but my therapist has been treating borderlines for 20 years and was trained by Marsha Linehan (the woman who created DBT) personally. 

I feel invalidated. Like am I just making everything up? Am I just looking for excuses for my behavior? I don't care for the label but having this thing I've clinged to as the thing ruining me that I have spent so many years fighting against be invalidated by my mom (who is ASPD spec and was diagnosed) makes me feel. So empty. 

How do people deal with the invalidation of their mental illness?
