Hi
Buckeyefan 
Yes, my DD has engaged in DBT skills group and therapy, you could call her a DBT groupie.
- 2016 one year, of both skills group and therapy weekly
- 2018 five months of weekly skills group
- July 2018 to date, weekly therapy session with a very experienced multi disciplined therapist. This is coming to an end soon ...
So since my last post my adult BPD daughter took too many anxiety pills and told her friend who called 911 and so the police and ambulance showed up at our house.
I'm so sorry, I've been there too, have written word for word in a previous post years ago.
How did your DD come by her present therapist? Has DBT ever been suggested to your DD? That your DD says she needs more help sounds promising as there is help out there and that is exactly what I said to my DD when she hit crisis in 2015.
There is hope.
