BPD with my child



I think my married daughter suffers from BPD and fluctuates between depression and happiness. She finds solace in food and is a heavily binges, due to this she has developed PCOS as well. She has a 1yr old child and is not happy in her married life.
Her History:
ADHD diagnosed and treated with medication at the age of 13urs-15yrs.
Case of CSA in young age due to which she had become aggressive and depressed both.
Self esteem issues and tendency of compulsive lieing.
She is otherwise excellent at creative arts (sings and dances well, writes good peotries) is an excellent cook. A good mother but has anger management issues.

Please advice me so that I can help her be happy again as for the sake of her health and my grandsons health.
