Have you told your Pdoc about your trouble with meds? Maybe you need to adjust the times you take them or just different meds all together. I would advise you not to take the online quizzes to serious they are very vague.
Many people have Bp and Bpd I myself have a few traits of bpd but my Pdoc isnt concerned, Its not a diagnosis you really want unless you are 100% but it takes a trained professional to determine it ..DBT is the typical treatment.
