Hi Yinks,
Welcome to the BDP family. Your daughter sounds much like my son, who is now 31 years old. It hurts to see our adult children suffer this way, knowing that the kind hearted and loving person we have known for many years is still in there.
My son doesn't sleep well either, sleep deprivation is a common problem for people with BPD. He has learned to regiment himself in order to be able to get up for work. It's still hard for him. Let's face it, we all know that when we don't sleep well we get irritable, and we have trouble dealing with things. Sleep is so important.
There is hope for sure. The good news is that through all the troubled times it seems you've managed to be able to maintain a pretty good relationship, you are likely her rock. It's awesome that you have been able to get her a diagnosis and to get her into therapy. That is something that many of us are still hoping for.
There are several book recommendations on this site, and I have read a few of them but there is another one out there that helped me the most. It is called "Overcoming Borderline Personality Disorder, A Family Guide for Healing and Change" by Valerie Porr.
You mentioned that DBT didn't seem to be working. Try to keep her in DBT as long as you can. That is great that you are going to try and find a better place but remember that nothing is going to change overnight, it takes time! Change is possible and it does happen. There is certainly hope for your daughter.
Does the DBT program that she is in offer a family program attached?
All the best to you and your family
