I si and I'm afraid of telling my T for a variety of reasons, one of them being I'm scared of being diagnosed as Borderline simply because of SI itself. That would really bother me. So, silver_queen to answer your question, I have no idea. Why label someone for life just cause they SI, when it could mean so many different things?
If you go to Google and write in Borderline Personality Disorder you'll find a million and 3 things. Good luck.
