To amuse and inspire you, here is my favorite image about this. My husband found it on the internet some months ago (we've searched and searched but can't find an attribution) and said to me, "This totally reminds me of what you do when you've been injured. You may have to change what you do but you NEVER GIVE UP." Best compliment I ever got.

I figure if we can do our best to keep that kind of attitude as long as we can...we'll keep figuring out something we can do. We might not know what it is today. But we'll find it.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
