Hang in there Doll.
Just went through something similar with a loved one and a broken leg and ankle in several places. 2008-9 was a hellacious year for me, but all worked out well. Took 8 months of therapy, but said loved one is up and around finally. I feel for you and have a taste for what you are tackling. You are a good son for helping out. Make sure that you take care of yourself along the way. Very easy to get yourself sick and run down if you are not careful.
My thoughts and prayers are with you and your Mom for a speedy and complete recovery.
