Is it worth it?

Sometimes I wonder if life is worth the pain. So many things in life are hard to deal with and just cause so much hurt. So many things can go wrong in a family. So many accidental mistakes have unfathomable consequences. I know I'll make so mistakes as a wife and mother. Will it be worth it? What if I do something without realizing and my child ends up scarred for life? I don't want to hurt anyone! *sigh*
