I debated posting this one at all, but in the interest of completion I figured I should.
I won't get too into this one, but these aren't just idle musings -- these are all thoughts I've personally have grappled with at one point or another, and the idea of juxtaposing them with a harmless children's cartoon for starkness felt surreal enough to go with.

Celestia's thoughts, as well, are my own. Boiled down enough to fit a comic (otherwise they'd be a huge rant) but true even if trite: when I finally got out of the worst pits of my life, I was in a place I couldn't even have foreseen myself being. My recovery, my upswing, was not just unanticipated, it was impossible to see from where I had been. It's easy to tell someone who's depressed "things will get better", but as someone fighting depression, that can feel like some hollow platitude. There are times when you can't even see the light at the end of the tunnel, can't believe there even could be one. The turns that improve your life and your mood might come from places you would never have expected, and so in the worst of it you'll look to the future and think "there's nothing for me there".

I'd been there.
And if I could go back in time and tell my more miserable self something, it would be that. I know it's trite, I know it's cliche, but it's repeated for a reason: Just because you can't see it doesn't mean it's not there.
And one day, when things are just a little bit brighter, you'll be glad you held on.
