When i'm depressed, i love reading about people who are also miserable
When I'm depressed with how my life is, I'll google my thoughts to find other people with similar problems. That's pretty normal. But I really love to hear them talk about how miserable they are, it makes me feel better, it actually makes me smile. And if it turns out to be an inspirational story, about how their life was really bad, but then they managed to climb out of it and they're doing really well now, then that doesn't make me feel happy for them, it makes me feel like shit again. Or if there are any comments that try to cheer the guy up, showing him how his life isn't actually all that bad because of this or because he always can do that, then that doesn't make me feel positive or motivated, it just makes me feel like shit again. I love the misery.
Instead of getting upset at other people's luck and success, work on yourself so you can be just as successful.
