Blended, Sometimes it takes a little while to get a response here... but when you do, well the people here are truly caring people and prayer warriors.
When I was married, I also lived in a new place... with no family or my own friends. It was very, very hard for me and for our marriage (part of many hard things that led to our divorce).
Are you involved in a church? I think that that can really, really help you. Not only so that you can fellowship with others, but also to have real live people praying with you and hugging you when you are feeling down. God strenghtens us through other people... but I tend to think that there is more strength and comfort in real live relationships vs. online ones (where you can't see or hear or touch the person). Maybe also some women have been in your situation and can give you advice.
As hard as it is, you need to "let go" of your daughter and literally entrust her to God. That doesn't mean you turn a blind eye and don't do anything, but all your worrying and fearing, etc... well, it will not help you, your daughter, or the situation. It is natural emotions to feel though, but God can give you the grace and strength to endure.
Have you read any books by James Dobson or Dennis Rainey? They are both really wise on parenting issues. They both also have websites. Dobson's is www.family.org
and Rainey's is www.familylifetoday.com
I hope you don't mind me asking, but how long have you and your husband been married? Why did you and ex-H divorce? How long ago?
Well, don't give up on the prayer forum. It just sometimes takes some time. Everyone is out praying and not here on the boards!
Read some Psalms! They can be really comforting in times of trouble. Hang in there. Part of your 13 yr. old daughter's distancing of herself from you is probably actually plain ol' adolescence and is actually normal. However, you have the complications of two families and that is not easy.
I would really encourage you to read some Christian books on parenting adolescents to help familiarize yourself with adolescents and what is typical for that age group. (Forgive me if I assume... maybe you've read stuff already?).
God bless. I pray that God gives you strength, wisdom, and comfort.
