The Universe is so vast. So much space, most of it with only the barest wisp of gas. Most of the solar systems we see in the night sky may not have life (we don't know yet). And yet here we are, a rare event in a vast Universe.
In the end it doesn't matter what you do. What you accomplish or did not accomplish. What awards were won or lost, life goals achieved or not.
Everything you can see (including the stars in the sky), everything you have ever heard about will be less than dust at some point in the far future. No statues will survive, no history books, no songs of glory. The stars will wink out, the galaxies red-shift past the point of visibility as they rush away from us. It will eventually be a vast, empty and quiet expanse, as the last of the black holes slowly evaporate.
But right here, right now, you are alive and able to experience the Universe. Yes, you may be in a shitty situation now, but you are still alive and you still have possibilities to experience something wonderful. It won't last, it never lasts, but that isn't the point. We all have to appreciate what we do have, when we have it.
Some people are in truly shitty situations, and legitimately have no way out, with no possible means to create even a little happiness for themselves. But for everyone else thinking of ending things prematurely, I urge you to consider how rare and precious you are. If you can give even a little kindness to someone else, it will have been worth it, because that's all that really matters, on our journey to infinity.
