I'm so sorry. My addict mom and stepdaughter are also dual diagnosis of mental illness and drug addiction. They are both bipolar. It is so hard to watch those you love who are in pain. My mom has had such extreme unhappiness throughout her life. As a child, I always tried to help her. I realize now that I can't help her, but I try to pray that her HP will watch out for her. I give her over to God, and what else can I do?
I felt frustrated over my mom's first hospitalization. They didn't keep her long enough to help her. After her most recent suicide attempt, she was more willing for help at the psych hospital. She learned some coping mechanisms and got referrals for outside help. It's amazing, but she is now doing better than I would expect. I think her medication balance might be a good one now. However, I never know when she will have an extreme down, and the possibility of suicide is real.
My thoughts are with you. Take care.
