Does anyone take medication for BPD or know of any that work?

My psychiatrist said he doesn't want to prescribe me medication because there are no studies done to prove which medications actually work for Borderline Personality Disorder. I am a firm believer in medication.

I have BPD, anxiety and I guess depression (not sure of the diagnosis now due to the new BPD diagnosis).

SSRI's helped my depression/anxiety for a short while but then started impacting it in a bad way. So I am currently not on any medication and my moods are erratic and my anxiety is slowly getting worse. My impulsivity is also getting more severe and I'm worried it'll just keep on getting worse.

Any thoughts?
