Prayers for you and your wife.
It will work out. You will get better and less dependent each day. From 2010 through 2012 ,I was in ICU 48 days with the home care aftermath. I was determined to improve every day just a little bit. Finally, i could stand so I practices standing longer. When I could walk ,i increased distance . I called in “Activity” periods. My spouse was key but I tried to lesson her burden a little each day. You will improve if you Work at it. I’m sorry about the accident. That happens— PRESS ON .God Bless you and your wife with strength ,healing and courage .
