Hello Mamaandy,
Welcome to the bpdfamily parenting board, here you will find lots of resources and help and support from other parents.
I am so sorry to hear of what you are going through.
You ask how to stay in contact when she is not rational and abusive, it’s all about learning a different way of communicating with her, there are lots of tools to help you, take your time and read the
TOOLS section which can be found to the right

Please know that you are not alone here, we have all dealt or are dealing with what you are going through too x
