Hello Alright and welcome to bpdfamily *Hi!
I'm sorry what brings you here and glad you found us for support, understanding and learning to move forwards. As you say it's a bit of a light bulb moment isn't it

Like you I'd never heard of BPD though while DD had been displaying symptoms through her teens, the dots did not join up in the medical profession until 2 years ago when my then 26yrDD was hospitalised and diagnosed.
It's great your DD is sharing with you what the therapist told her about her latest possible diagnosis. My DD has just completed 12 months DBT the skills she has learnt helps her better manage her emotional disorder as she works towards wellbeing, recovery and independent living. I see this as my daughter's journey and her responsibility to recover independently from me, I'm aside her learning the skills to your right that my DD is learning, me gaining an education to keep up with her, validating her efforts and her fight to be well.
From what you say it sounds like your DD is fighting to be well, as you are paying for her treatment can you ask her what it is, again?
Small gentle steps help.
