More of a realization than a quote: Death offers nothing that life cannot offer.
I am an existentialist, and I do not think anything (that is not terminal, I guess; haven't though about extreme conditions) is worse than death. So, every bad thing will pass. Every depressive bout and anxiety attack shall pass. Hopefully, your rock bottom shall pass too. And may be, at the other side, things will be better for you.

So, while the image itself might be AI, the mural/meme definitely predates AI.
Hated every moment of it!
