I have been watching a lot of youtube videos. One of them was on bpd and medications. There are some that have been proven to help with various aspects of BPD. I didn't find a med that worked consistently enough but wasn't on the ones they talk about. Maybe that would help. I mean it's not a total fix but it might be the break you are looking for. The video it was posted by NEA BPD titled: The treatment of BPD with medications: A neuropharmacologically based approach. If I were to try meds again I would be trying the meds he lists as there's evidence those meds work. Maybe get a referral from the new T you are seeing.
