Hi mommapanda and welcome
I’d like to join BPDexhausted in welcoming you to bpdfamily .
I'm glad you found us, parents here understand what you are dealing with, you are not alone. It sounds like you have a loving, respectful and trusting relationship with your daughter, despite her struggles she's able to reach out to you, she knows.
Acknowledging and accepting is a very brave thing for our children to do and what I have learnt equally important is how we support and that requires us to be prepared to change, to skill up by using the tools and lessons to your right

it starts with us

Have a look at listening with empathy experts say it's the most powerful tool, it certainly helped me in those early days, putting myself in my DD's shoes.
I want to share this with you
how to get a borderline into therapy every situation is unique my 29DD was desperate to understand why she was struggling and the diagnosis validated her feeling, provided her relief that there was help out there, she's just completed 12 months DBT and continues working on her recovery.
What do you think your DD may feel is the best way forwards for her at this point?
