dave speaks the truth, but in our world many of us have become unaware of love even when its right infront of us. the one thing that helped me become more aware was the enviroment i put myself in. for teenagers today the enviroment is extremely high speed (for lack of better descriptionn) not allowing them to stop think and dip below the surface. what helped me was finding a peaceful and quiet enviroment (nature). i dont know your duaghter but she may be opposed to this b/c its scary to dip below the surface into the unknown. but if she is still uunhappy even after all your lovin try a new quiet enviroment so she can think.
