Beyond that, I think of suicide as more of something to put off than something to "cure". What can you do to put it off for a bit longer? Sometimes distraction, sometimes drinking, sometimes just getting out into nature somehow.
There's a lot to be said for detaching completely from poisonous people and environments. You might think that you can't leave your awful job, declare bankruptcy, or never talk to your mother again, but you can. And maybe you should.
One thing to consider is the subjective acceleration of time. We all experience that each year seems to pass quicker than the one before, for the most part. I realized at some point that this makes suicide a lot less urgent, at least at my age (50s). Putting it glibly, we'll all be dead soon enough--what's the hurry?
