Hi FaithinU,
Love your username!

Welcome to the Parenting Board, we are so glad to have you join us and look forward to learning more about you and your daughter and how we can support you.
It's good to hear that your d has a diagnoses and is on medications that seem to be helping her depression and anxiety. My d was on 2 meds for the same thing and now she is down to one and a lessor dose. The meds do help level out some of the underlying problems and they may learn skills more easily.
How old is your daughter? Does she live with you? What is your relationship with her like?
One of the most researched therapy models for BPD is Dialectical Behavior Therapy, a form of CBT (Cognitive Behavior Therapy). Has her doctor mentioned any treatment modalities for her to look into? Is DBT one of them?
I look forward to hearing back from you.
