I am so sorry to hear that your daughter has left. Have you reported her missing to the police and posted up signs in the area? I know there are some excellent systems for finding lost children out there.I have also found that sometimes runaway children can be found in the most obvious of places, because they want to be found without giving themselves up. If it is a cry for help, then think of places that your daughter goes to and people that she is involved with including friends and family.  I Perhaps if you provide more details people from your area could keep their eyes open for your daughter. I really hope and pray that you find her soon.
