Hello Sososotired 
Welcome to bpdfamily.com. It sounds like you and your daughter have been through a lot. I'm sorry you're struggling with all of this.  
I read in a different thread that your daughter is adopted. Sometimes adopted children have some special emotional needs. When was she adopted? How old was she? Is she diagnosed/in therapy? Are there other children in your family? 
It sounds like your daughter is self harming, what a scary situation. How are you coping with everything you've been up against? Are you working with a therapist to help you through? 
Thank you for your concern. She was adopted as a toddler into a family with two older children.  My other family members are mentally healthy.  Her siblings are in college and doing well. 
She was diagnosed as BPD by a competent psychiatrist. As a child, she was not diagnosed to be RAD.  We underwent attachment therapy when she was adopted. I believe she is attached to me, dh, and her other family members.
For the last 2 years she saw a personal therapist, but her recent move ended this relationship. She refuses to seek therapy at this time after she was fired by her new therapist after only 2 sessions with her.
