As a Christian and a Father I have never been able to understand how a parent could turn their child away, its just too hard for me to consider. The Lord has told us not to judge but to love. The best advice I can give you is to love your daughter and remember that she is a child of God.
I too am new to this website. I am glad to see support and love for everyone, if only this could be acheived on a grander scale.
