Screwedup,
Did not know that some jobs will discriminate based on BPD. That is terrible... they should not be allowed to do that. It would be tempting to do the same thing as you are doing, to ask the psychiatrist not to use that label. Do you mind if I ask, is this in the United States? I thought it was illegal here for companies to ask for your medical records. Given that the BPD diagnosis is itself unreliable and really invalid as a medical disorder (i.e. different therapists often diagnose the same patient differently), it doesn't even make sense to restrict someone from work based on such diagnosis.

I'm not advocating this, but it may be possible for you to use another, less stigmatized diagnosis (like "depression") to get another form of useful treatment, and then retain the ability to do teaching sooner, if what you fear is right. I will admit I did this in my later years of therapy. I stopped being diagnosed as borderline (which I actually was not, in terms of the 9 symptoms, by that point) and instead asked my therapist to use another diagnostic term which she did.... "dysthymic disorder".... whatever that means It was funny because I was feeling well most of the time but I was officially labeled with this disorder that means you are really depressed.
