I have BPD and bipolar type 1. I did dbt for a year and a half and it did nothing for me. I don't relate to a lot of bpd symptoms like jealousy, unstable relationships, dissociation, so I don't know if the problem is that I just don't have bpd or I didn't put enough work in.  I feel like a failure. I found this miracle therapy patronising, dull and childish, and i didnt get anything from it. I don't really self harm anymore but if I'm honest it's because I can't be bothered and the cleanup is too much. 

Anyone else?
