I shake when I'm nervous. How do I stop it?!

When I feel nervous or anxious, I shake a little. It doesn’t show, but you can feel the tremor. And this is embarrassing because I partner dance a lot as a hobby and I’m sure all my dance partners feel the tremor on my hands. Nobody really says anything, but when I tried dancing with my friend, she said she can feel the shaking when she dances with me. If she feels it, then I’m sure all my other partners feel it, but are just being polite by not saying anything.

This is so embarrassing. How can I get rid of this shaking when I get nervous and anxious?
