hi hurtmomma

,
It is so hurtful and such a sad situation for us. I expect you feel a bit confused as to what to do... .
sk8mom has a point that we often reward the wrong behaviour because we are fearful of the blowout that will ensue. What is wanted is a circuit breaker of some sorts, perhaps.
The circuit breaker in this case is probably for you and your dh (dear husband) to read up on 'values based boundaries' and to begin to define what you need to do to protect yourselves from your dd's (dear daughter's) disregulated behaviour. Have you read the information on this? See link below:
https://bpdfamily.com/content/values-and-boundaries It also helps to understand why a pw BPD acts the way they do: what they are doing and what is going on in their mind might not correlate. It helps to learn as much as we can. This is the link to the board where there are all sorts of good resources:
https://bpdfamily.com/message_board/index.php?PHPSESSID=dfeeba0bb9be3fc9dd877e0501d26d4c&topic=114267.0The sort of therapy your T referred to is DBT. An especially successful form of therapy for pwBPD, but I would be very careful before I said no more family activities until you start DBT. First, does your dd have access to DBT? DBT involves an individual therapist as well as skills training, both at least an hour each a week. Is this available to her? It would be unfair to say you can't be a part of the family unless you have therapy and then find out there is none available to her.
It is indeed baby steps that we take and this is a long journey we are on. There are no easy solutions. It has taken your dd years to get as bad as she is. She is not going to get better in a hurry. So, we need to learn what we can do to make things better.
Our first rule here is to take care of ourselves. While we do this we learn as much as we can about BPD. And we begin to practice the tools we need to use in our lives: values based boundaries and validation. Simply put, that's what to do.
Hurt momma, you are in a safe place and a place where we have people who understand what it means to be the parent of a child with BPD. This is a wonderful place for support and guidance. I am glad you have joined us.
Cheers,
Vivek
