Need exercises/workouts I can do while injured

So I've been dealing with a sprained ankle for the third summer in a row. This time, however, I have been told I cannot bear any weight on my foot. I need some help with exercises I can do. I spent the second half of April and all of May doing nothing (but my PT exercises) and am tired of it. I went into the pool yesterday to "swim" but the kicking action of swimming was too painful, so I spent 45 minutes just floating in the pool until my friends and I were tired of being in the pool.

For more context: I'm hypermobile and injure really easily, but am also overweight. I used to be a professional folk dancer, and still have a ton of muscle/strength from that, even though it's been 13 years since I last performed professionally.

walking, swimming, dancing, and hula hooping have been my past workouts that I've loved doing, but for obvious reasons, I can't do any of them right now. So any advice is greatly appreciated!
