I've been seeing my therapist for a long time and she believes I have bipolar 2 and PTSD. I recently got started with a psychiatrist and he's like yeah you definitely have BPD. I think he's right. It's the first diagnosis that really fully describes my experience.. My therapist kind of just rolled her eyes when she heard his diagnosis and says that BPD is just PTSD by another name. I felt so invalidated and started crying when she reacted that way, which she followed by asking me why I felt I needed a label anyway? I tried to convey that having a name for it helps me, but I don't think she gets it. 

Has this happened to anyone else? Having a diagnosis that makes sense feels like some sort of anchor to hold onto, but when she tells me it's not real I feel lost all over again.
