Depends what that means.

Why do I dislike my current situation? That would be nuanced, at minimum, to explain to a Gazan or Rohingya, but on Lemmy I can just say: "My situation is objectively bad."

Why aren't I joyful more often? That's just how I'm wired, it doesn't matter what's happening.

Why do I experience negative emotions often? First off, I'm not sure if I actually have more than average. Probably less. Beyond that, I don't really know. If I was in a better situation, would it stop? Would I find some tiny detail to stress over, instead? How objective are we even about remembering what we've felt over time? There's not enough information.

Why do I feel wronged by the world around me? I don't, really. Shit happens. I'm lucky in that I actually know that.
