Hello. I was diagnosed with BPD back in 2017 but later on, with a different doctor, I was told I don't have BPD but instead PTSD, DID &amp; Bipolar Disorder. 

So my question is this: How do you know which diagnosis to claim when one doctor says one thing and another doctor says another? Do I just go with the new one since she said I don't qualify for BPD?
