I do pilates which is different but you might like it too, I started last January when I was very depressed and off work, and it is good for just getting you moving gently, no matter how bad I felt going in I always felt a bit better coming out and bonus of not being sweaty! I still do pilates now, I absolutely love it. Its definitely a good thing to do a taster session of something before you sign up and also maybe you could find something that is as easy as possible to get to so the journey itself doesn't feel overwhelming.
