Hello Agnixa
Welcome to the community I'm glad you found us, you've come to the right place for support, parents here understand what you are dealing with, you are not alone. Parenting a child with BPD as you say is exhausting and that's why its important we take time for us to self-care, you must be very busy, do you get time for you? That's hard for your husband to be accused of terrible things, it hurts, how is he managing that?
You are doing great calming down your daughter, there are tools and lessons to the right

skills that can be learned, many of them are not intuitive and require a lot of practice and patience. They do work.
You've been through so much this year, what is the most challenging behaviour you are dealing with are the moment?
Glad you are here with us.
