I don't know much about suicide. But I have an idea about suicide prevention. And I learned it from Rocky IV. Let me share two scenes that explain my theory:
The obvious lesson should be that there is no easy way out; no shortcut home. That what you need to do after you've endured yet another wrist-slitting Monday is sprint up a snow-covered mountain while listening to some super synthy '80s music then beat the crap out of a giant, spiky-haired Russian. It will, undoubtedly, renew your purpose. And, quite possibly, you'll vanquish Communism in the process.
In the event that this John Henry mission leaves you at all unsatisfied, then you can also drink two bottles of wine and pass out at 10:30. That will work, too.
