the problem i have with deliberating these sorts of methods is that there is plenty, plenty of time to regret what youre about to do.
there's no turning back, whereas with a gun you can think about it up until the point you pull the trigger.
but yeah, giving yourself the only option to jump while youre stressing tf out is no way to go.
if you feel it's worth going through that sort of pain, you mind as well just live, life is full of those lessons of "the pain is worth it".
