Please help, I’m a problem player

I’ve been having a problem in DnD. I love the game, perhaps too much.
I keep finding myself trying to control the other players (telling them what they should do, or where to go), and I want to stop.
I’m ruining everyone’s fun.
And I don’t know how to stop!
I want everyone to have fun, but I’m having a hard time restraining myself. Anyone else who has this problem: how do you stop yourself?
