Ihad a similar experience. When I was given a handout on BPD I asked how the doctor could differentiate between BPD and the sequelae of the traumatic brain injury I had a few years back. Of course there is no answer. But I found it very confusing. I attempted on the ward and was told I was just attention seeking. After spending the weekend in the rubber room what I learned was that is not a safe place for me. So building a safety net is confusing for me. I have to keep myself safe. I second guess reaching out. Am I just attention seeking. Really gets in my head this issue. Anyway dealing with suicidal ideation on my own has been really tiring.
