I am so sorry for what you are going through. I can relate. I too (as of now) am powering through. I'm exercising to keep my core and legs strong, using a focal point when I move, being intentional about engaging my core when I move, taking a hiking stick for balance when I walk in the neighborhood etc. Now I'm researching grab bars for the tub/shower. Sucks. I'm also trying not to have this SFPN drive what I can do in life or limit fun with friends and my significant other. It's miserable. Not how I thought I would be functioning in my 60s. I've always been really resilient in the face of other things I have been faced with in life, and am calling on that resilience again.
