I don’t think that list is very helpful. It sounds like prevention thru guilt and shame, something that many people who are suicidal do not need.
Many people commit suicide because they want to escape the unbearable pain that they feel, many times due to the fact that depression can skew their view on their worth and their problems and they lose hope.
Getting help for depression can sometimes get that person around to the next corner.
I can understand that if someone is in actual physical pain, there is usually a physical cause, which may be incurable. But psychic pain will not kill you; it only makes life difficult. Who ever said life should be easy, or that you should NOT feel pain? Pain is not necessarily a bad thing. It means you're doing something wrong and you need to fix it. Instead of listening to Prozac, people should listen to the pain. And I agree, they should get help.
