That is rubbish, religion has nothing to do with boarderline personailtiy.
It is a problem, that ended my first marriage. I was cutting myself, and still to this day hate myself and fail to properly take care of myself.
I have Boarderline Personality, Bipolar, PSTD, ADHD, and OCD.
I would like to talk to you further about this, I send you an e-mail please get back ahold of me, it is nice to have firends with the same problem.
By the way my name is Pammila and I am 37 been living with borderline personality most of my life.
The funny thing about it, is that some relationships it was a problem, and others it was not. Thankfully I am remarried and now it is not currently a problem, but I would still like to help you out with this problem.
I can't remember the name of the book, but there is a training book for borderline personality. That you should get, I got a copy here and will try to find it and get back to you with a name. But it is training on how to act normal around others.
