This is probably useless to anyone else, but this is an idea that popped into my head once when feeling suicidal: "if these is really the ultimate reality, and not a simulation, and since I have no reasons to believe that reality is not "ultimately" real, then suicide is simply something I'm not allowed to do! even if I reduce anything to pure selfishness, I simply cannot let the ideas in my head die, I am responsible for them! I must help them spread, I must help them develop, because they might completely change the world for the better! and no matter how small the chance of one of my ideas significantly changing the world, and of one of these ideas not being in other people's heads too, this chance simply cannot be taken... I cannot risk killing an idea that could change the future of the entire universe!"
...I know, it's probably one of the most narcissistic things you've ever heard, but as even Dalai Lama said: (paraphrasing) one must be able to love himself in order to be able to love others.
