busymind79,

I'm glad you've found us.
I'm sorry to hear about what has been happening with your daughter it has to be so scary watching all of this go on with her.
Do you feel the RTC is being of help to your daughter? I'm glad it is at least giving you a bit of a respite. Are you receiving support? Therapy? It is important that you don't forget to take care of yourself so you can be there for your daughter. Has your daughter been given a diagnosis? Typically BPD is not diagnosed this young however that doesn't mean that she isn't displaying some of the behaviors.
Have you had a chance to learn about BPD? Do you think your daughter displays the behaviors? A good book to read for a good overview is
Stop Walking on Eggshells: Taking Your Life Back When Someone You Care about Has Borderline Personality Disorder by Randi Kreger
I'm on this site because my SO has an uBPDxw so I'm coming at BPD from a different angle than you are but I want you to know this site and it's members have been incredibly helpful and supportive to me and I know you will find them the same.
I suggest you visit the
[L5] Parenting a Son or Daughter Suffering from BPD Board there you will find other parents who will know just what you are dealing with. Please post your story, questions and concerns I know our members will be supportive, have good ideas and strategies, and will be able to direct you to tools that you might find helpful.
Again Welcome
