If you are suicidal, take the time to pursue the wild dreams you've always thought insane. Go on that crazy hike around the world, you'll surely starve to death. Go climb Mt. Everest, the cold will end you. Fly out to Paris, spend all your money on expensive food and alcohol and talk up all the girls, you'll be left there with nothing to do but die if you can't get back.
Don't just swallow pills, it's terribly boring.
