This applies to most, if not all, people with bpd. Those of us with bpd learned ineffective coping mechanisms from an early age. There is no pill that is going to cure that or give you new coping mechanism.. You learned bad coping mechanisms over years, and it will take time to learn new coping mechanisms.

Now most of us have bpd along with anxiety, depression, bipolar or whatever. A med may or may not treat those symptoms associated with those illnesses. So you could be resistant to treatment for those conditions, but it would only be those conditions.

Meds will be of virtually no use to bpd itself. Like the person above stated bpd needs to be treated with something like dbt. Even that isn't 100% effective..
