Borderline Personality Disorder/suicide threats.
I need suggestions as to how to deal with a person who has a severe undiagnosed borderline personality disorder. She daily throws tantrums, is invasive, breaks objects and threatens suicide, but becomes believably sane if the authorities are called in and threatens to make false allegations against me. She is quite delusional and refuses to believe she needs any kind of therapy and thinks all her problems are the fault of others. Mostly, I'd like to exit, but am afraid all hell will break loose. I have a heart condition and while walking a tightrope, don't feel ready for an all out war.
