Im sorry, but death is final. There's no taking it back. Life sucks, I've had a bad one. But it has gotten better. The best thing to do is think about yourself and what u need to do. Think positive and how to change things that r going wrong. If you feel like no one loves you,you have have to love yourself more. put your head high and do for yourself and remember your worth so much more than what people say or think. God loves you
