Does anyone here have an adult child with Borderline (BPD)? I have been wondering for several years now whether DC2 might have it. I took an online test today and answered the questions based on my observations of my daughter and what she has told me and the result was possible severe Borderline (BPD). I am not a clinician and it's just an online test, so I am not putting too much stake into it. If anyone here has experience with an adult Borderline (BPD) child, I would love to hear how exactly the disease manifests in your case. I am looking for examples to compare to my situation.
