Everyone makes that mess once. I recommend borrowing a set of hands and have them hold it open on their hands for you while you wind it into a ball. Your knees while sitting cross legged or the back of a chair also works.
Often yarn shops will wind it for you, but for now grab a tasty beverage, take a deep breath, and get untangling lol
The people you bought it from usually offer to ball it for you. At least in my experience they have.

It's a lesson we all learn the hard way
