The true tragedy is that a part of what makes a person dies when someone passes away and something replaces that, is it love, despair, anger that's up to you, let it mold you into something greater and let your brother be the hero who made you greater.
But don't be sad, they don't die, even those who don't believe in the afterlife, people who pass become a memory, and that memory becomes a treasure that you will have for the rest of your life.
