How do I stop feeling jealous of successful people and celebrities?

I'm in my mid twenties, jobless, and just started college after all my peers already graduated. On top of that, my major has no clear future and I don't even like it. I still live with my parents, depend on their allowance, and have zero money for rent or anything else.

Whenever I listen to music, watch movies, play games, browse apps, or watch YouTube, I feel like a total failure. Even reading about other people's lives or looking at those around me hurts.

Most of them made it big in their teens or early twenties. Even regular people around me have achieved things I haven't, and at a much younger age, like getting good jobs, dating, traveling, and graduating early.

How do I stop this constant envy?
