If you truly believed what you said you believe, you'd wish you and all humans and all living things die asap, instantly, and painlessly from supernova or something. That way, all living things could leave together this horrible world you said. Death is better than life.

You might also wish that the Big Bang had produced matter and antimatter the exact same amount, so they would have perfectly canceled out, and there wouldn't be any matter at all in the universe. Nothing is better than something.
