Something I don't understand: On websites about suicide and informational videos, there is always a message akin to If you are suicidal or considering suicide, IMMEDIATELY call 1-800-SUICIDE!
If someone is so gone she is going to attempt suicide, then she isn't going to call for help. Why would she? She wants to die, and doesn't want anyone to get in her way.
I guess this might be based on the assumption that suicidal people don't really want to die; I don't think that assumption is true, or didn't seem to me at least in my suicidal days. If I had seen that number on the Internet, I wouldn't have called it.
There needs to be a different approach to this, but I can't say what it is. Perhaps education about depression, SI, and suicidal thoughts provided in public education? Don't think it'd do much, but it might relieve some stigma...
