adult child mentally ill, holidays

My adult daughter has a serious mental illness diagnosis, rejected Christ, and moved far from home, She is talking about visiting for Christmas. Please pray for her salvation, protection (she has no street smarts and does so many foolish things). I ask prayer for the Lord's mercy and peace in this visit...there's so much hurt between her and her sister. I am very tired - please pray for God's healing touch in the bleeding heart wounds in this family. I know He loves us so much and has been using the prayers here so much.
