Hi Bobbie-
I don't have the voice issues, so don't have any advice there. However, you are doing the right thing in being active. Don't overtax yourself and make sure you do lots of stretching and range of motion exercises. I've experienced great benefit with having a physio help me with balancing exercises and it's really helped me with an awkward gait.
Mostly I just wanted to welcome you here, disappointing as it may be to find yourself here(!), and know that there's a lot of knowledge, reassurance and experience people have to share.
