I forgot to add - as things change - focus on the things that you CAN do and try not to dwell on the things you cant or wont do anymore. Believe me - it is HARD to do. It is something I have to remind myself of everyday. Staying as positive as possible is very important and overall good for you. This along with a good exercise routine, good diet, regular times of rest and a good stretching routine also helps a lot. All things we should do regardless of our afflictions.
Starting off on these things NOW before they become more difficult is something I would highly recommend. Then when things are changing - you wil already have these things in your routing. You wont have to learn them later when learning might be a challenge. For most challenges there is a way around them.
Her is an example of thinking of what I can do instead of what I cant do. I was doing some home PT for a couple of months. We thought yoga would be something good to try.
Immediately I thought of the many reasons I couldn’t do that. For every reason I gave - he gave me two ways to work around it. From that I learned this lesson - focus on the abilities!!!
It might sound weird - I now do chair yoga and find it very therapeutic.

Peace
