This is your life... whatever happens, is your life. There is no "it should be/it shouldn't be"
embrace it or throw a tantrum. I've thrown many tantrums, but it got me nowhere but miserable. So I choose Joy and peace within myself and those around me... whatever comes my way. When you have cancer, or...? there is a possibility you are going to die, do you really want to spend the rest of your life, and, those around you, miserable or grateful?
