So for a long time now I have been convinced I have BPD. I thought, and still do believe, I fit the criteria perfectly. Today I have a video call meeting with my therapist and a doctor who specialises in autism, BPD and other things. At the end of the call he told me he thinks I have Bipolar Disorder instead... I'm just kind of shocked. He does know that I was thinking I had BPD and he also read the 4000 word letter I sent to my therapist opening up to her about my feelings and what goes on in my head, specifically regarding the symptoms for BPD. I have never in my life even considered Bipolar disorder before. I agree that I fit the diagnostic criteria for it but I'm so confused. It's just come on as a bit of a shock. I was thinking that maybe Bipolar and Autism overlapping might create something similar to BPD??? I just don't see how Bipolar would explain the abandonment issues, the intense jealousy, the splitting/black and white thinking, etc. Although everything else makes sense to me. Just thought I'd share today's experience.
