Concerned parent and grandparent

[SilentTide]

I found this book while reading “The essential family guide to borderline personality disorder.” Our daughter was diagnosed with bipolar and BPD a year ago.
Her symptoms started as a teenager about 10 years ago. We walk on eggshells all the time and her personalities and outbursts have controlled our family for so long, that many of us are broken emotionally and even suffering physical ailments from the stress.
She has two small children, and they all live with us. We would ask her to leave if it wasn’t for the children. We are the only stability that they have. We feel stuck and alone.
We’re looking for support and any advice available. Thanks!

Our objective is to better understand the struggles our child faces and to learn the skills to improve our relationship and provide a supportive environment and also improve on our own emotional responses, attitudes and effectiveness as a family leaders
