ewie23, I wrote a long post and then lost it, but here's a summary of what I wanted to say:
Klonopin is addictive and has terrible side effects including loss of memories and emotions. Its not safe, nor will it address the core symptoms of BPD. I would advise you to talk to your doctor about your daughter tapering off it.
Your husband sounds like he needs therapy as much as your daughter, maybe more. It's totally inappropriate for him to be saying and doing those things. He might have some combo of BPD and PTSD, I don't know.
Psychiatrists and the psych industry in general just doesn't deal with BPD very well, either in kids or adults. It screws with the system, and they don't like that. That's why BPD has had the reputation in the industry of being a "trash-bag" diagnosis that therapists give to patients that they don't like, can't control, or just don't understand. It's important to read good books on BPD, listen to people who have it, and trust your instincts and your daughter's instincts, because the "help" you get from professionals is not always going to actually help.
And remember that physical health is really important! It's simple and cheap to exercise, get fresh air, and enjoy nature...
