I try to do the opposite. Doing things that are good for me, just me. Pursuing anything greater than myself is too much like mania, right now. You shouldn't have to rely on it to feel better. It should be a choice to do good, not one to forget about yourself.

But you're right that suicide is far less likely if you focus on something greater than yourself. But it doesn't necessarily make you a better person. Just one who does some good.

Many focus very much on themselves and don't want to end it. Not everyone is in the same kind of hell. But going through hell is also rewarding, so there's no reason to complain. And there's every reason to compare to make everyone's life better.
