BPD - my daughter needs help, i cant find it

I took my 22 year old daughter to a mental health place 2 weeks ago, because if she didnt get help im scared shed end up dead. she has depression and was told a few years ago she most likely has PTSD, but she wouldnt go to see anyone for help. Her life is spiralling out of control, she has shocking anger and rage episodes that frighten me, she has a drug addiction, but she is mixing a cocktail of diffrent things, self harms, and she had told me she just doesnt care anymore, lifs to hard now and shes hhad enough. So at te firs appointment a mental hhealth professional spoke with my daughter, then bot of us together, i told them everything and how extreme her situation is, but they seemed to think it wasnt extreme enough for them to take her on and i should just get a mental health care plan and talk to my gp. I have done all that, but it didnt work, she needs more that just a councillor to talk to. So they booked another appointment for the following week with a psychiatrist, who diagnosed her with BPD. but thats all he told me and booked another appiontment for next week. I dont know if i should go and get the mental health care plan from my gp still, or if they will do it at the next appointment, they gave me no information or any advice as to where things go from here. After reading up on BPD when i got home, its my daughter to a T, but she is to the extreme. I dont know where to get more help or where to go now
