My personal beliefs about God put aside...
God sees every life as equal, and values each one as important as the other, but it is us and human beings who put different values on each other. You may not see yourself as being worth while or valuable and feel that God should just take you away from this world, but God certainly doesn't feel this. He doesn't want your life to be wasted, he wants you to see yourself as he sees you, as a person who deserves to live and has a place in this world just like any other.
