ground hog day / kill yourself. literally, kill yourself, but do it FOR something. what would you kill yourself to achieve?
When I went to execute on step 1 of this plan, life beat me down harder and I decided to stick where I was not add more stress to the situation, which made me feel useless and worthless.
My point being, telling people who were once suicidal to kill themselves is probably not a good idea, even if it's for the shock and awe factor.
I'm not an idiot though. We live in a world where people react and do things. Life is kind of like Groundhog Day. We can weave through it in all sorts of ways. And when I'm feeling persistently useless and worthless I start to think about how to end that. and then I think, oh yeah. I can change how I live, even radically. that useless worthless feeling is a clue telling me to change how I'm living. (it's also a clue to go to the tanning salon). There is no "right way" to live a life. There is just living life. And if life sucks, we are free to change things. And I have found dreaming big, swinging for the fences, trying the impossible, dying (or living) for a crazy idea is a better alternative than a short leap.
So before making that leap I asked myself what would I rather do? And I didn't go to school that day. I did go to my job at KFC before returning to my roach infested apartment. My grandpa gave good advice: "Always run towards things." But sometimes you have to move away from something to get the freedom to change direction. Suicide just doesn't let you get to that change direction part.
I aslo believe that learning to meditate in the library while sluffing class in HS helped me to gain a little distance between my consciousness and my problems. Practicing meditation is particularly hard when depressed but it does seem to open a space of freedom between the emotions of depression and oneself. Which is why I recommended it to the OP.
