Hello, Ed1954 & I'd like to join
corraline in welcoming you to this site, and to encourage you to read the links that she provided for you. Welcome, also, to the Parenting a Son or Daughter suffering from BPD Board
I'm really sorry that you are having troubles finding a Psychiatrist in the New York, New Jersey area. This link should help you with that: The
National Alliance on Mental Illness has a search bar where you can enter your location, and could give you resources convenient to you, and all sorts of other information. Since you mention that she has BPD and also substance abuse problems, I do want to mention that a Dual Diagnosis Program would be something you might want to look into. It was the only Program that diagnosed my own adult (37) son's BPD and treated it correctly, and set him on the path of recovery; almost 18 months later he is still clean and sober (from a Heroin addiction) and doing really well.
Like corraline said, let us know more of your daughter's situation so we can guide you better, Ed1954... .
