Life
Maybe life has no meaning. Maybe at the end of your short life its oblivion. I mean it's not all bad. At least you know there isn't hell. I was never a big fan of hell. Permanent tortue? I don't think anyone deserves that. Actually maybe any person who killed another human. Because if life has no meaning, then you robbed another of this whole experience. You sent some entity to oblivion.
Just be happy. Life has no meaning, so you should just be happy. That's the only knob you have control over. Choosing to be happy is the very thing that's going to save you. Save you from joining some cult. Save you from people who don't deserve you. From jobs that don't deserve you. You will shine all the way to the top. Dazzle the world with your impenetrable smile. Don't let them see you hurt. Be strong. Laugh when you fall. Nothing shakes you. You're an iceBerg, and the world is your titanic.
Don't attach secondary meanings to things. You're sad. Be sad. But you don't deserve to be sad. Don't blame yourself. Remember life has no meaning. Things happen. Ups and downs.
