I am so sorry. You are not however in control of what your daughter does. It is so hard. We had to decide to choose our innocent grand over our adult daughter. Lawyers are being spoken to and my daughter is not yet aware, but she is in no condition to raise a child. She is homeless, jobless, hooked on pot and maybe more.
It is sad that we are put in these situations. We just want to love everyone, help our kids and have peace. We mean well. You mean well. My heart hurts for your pain.
In the end we have no say over our grown children. I think they often use our fear of them hurting themselves to get us to back off. My daughter has threatened to kill herself many times. If she was trying to scare us, it worked.
I wish you blessings from God, if He is in your life, and send you love and light.
