How should I go about asking my doctor that I may have BPD?

[SmashingPumpkins13]

I have an appointment with my family doctor coming up soon. Me and my family think I have Borderline Personality Disorder and I really don't know how to bring it up. My doctors from Zimbabwe and sometimes he doesn't understand where I'm coming from at times. How can I tell him in a positive way so he'll give me a better dialysis? I don't want to be rude or anything
