But why would it start vibrating out of nowhere?
I'm not sure but I really need some help.

So you're saying that it vibrates when the car is moving a lot between 25 and 30 MPH.

With the car stationary and in neutral, it doesn't vibrate.

You have a bad u-joint.

Pull the driveshaft and inspect the joints. Any amount of slop, stiffness or "crunchyness" indicates a bad joint. Very common issue as these cars age since the u-joints are non-servicable from the factory.

At this point you can buy a new OEM shaft, replace the joints yourself (pain in the ass), have a local driveline shop do it, or buy a new aftermarket shaft from the local driveline shop or Mazdatrix.

There, done.
