Hi bitterdregs; I'm sorry you are struggling with this. Does your daughter take medication? It's really important for her to get Professional help, but in saying that the effort and work is done by the person who is diagnosed i.e. I have to take my medication, exercise, eat healthy, go to therapy, go to work; put effort into my life etc. No one can do this for me, but I appreciate my support team (Psychiatrist, therapist, a few friends, and my horse)

It's also important for you to set boundaries with your daughter. Yes at times people can say and do horrible things to each other. It may or may not be a symptom of the bipolar and in reality it doesn't matter. You decide how to react and whether to engage with her. The book in my signature is for families, spouses etc. and it's excellent. I hope it helps.

With your grandson that does cause me more concern. Does your daughter have people in her life that can help care for him when she isn't well?
