Am I misunderstanding stimming?

Hi,

I wanted to ask about stimming. People talk about stimming being a good thing and something you can do to help regulate yourself. I stim when I'm stressed but it doesn't make me feel better, its just sort of a compulsion.

Is that what it's like for other autistic people?

Because I've been feeling really jealous that other autistic people talk about stimming as if it is this magical outlet that makes them feel amazing, but I started to wonder that maybe I misunderstood how stimming benefits people. Maybe it's not like how I imagine.
