Lamotrigine
"Been on this for about a year, 100mg. Took away my libido, I still get depressed/suicidal, still self harming. It's made me lose my self. I've been told that BPD can only SOMETIMES be managed with medications.  I also take an antidepressant 75mg. It helps if you get good support- good therapist and good doctor.  I really hope they come up with better things to treat bpd."
