I really am so sorry to hear about that. Even though I suffer none of these ailments myself, I've witnessed my elderly parents and friends (yes, I have elderly friends) go through coping with this negative permanent change to their day to day existence, and it is heartbreaking. It is an experience I can only logically expect to one day viscerally experience myself.

I wish I could offer you more than sympathy, truly. I hope you can find some peace and joy in the probably brief reprieves from your sufferings.
