Hi woogiebooie,
I'd like to welcome you to the family. I'm glad that you've found us, I can tell that you care very much for her, you're trying to get help before you make the P appointment, I can understand how difficult it would be to watch someone that you love go through this. My advice is if she's harming herself, take her to the local hospital or call your local emergency services. It's 's something that she's going through at the moment, it's not personal to you although I understand it can easier said than done to depersonalize the behaviors.
The P said that she had episode the last time, was she diagnosed with BPD? I just want to say that it helps to talk to others that can relate with you and offer you guidance and support, you're not alone.
