Hello, again this evening @forge55. You certainly are a survivor and those are excellent questions given your special needs. I can only visualize it for you. I actually ran my business, using one hand. It was amazing how my customers stepped up to help me. I became a pretty good ambidextrous writer for sales receipts. I didn't do so well on the computer keyboard.
What I did have was an amazing friend who arrived shortly after I came home from the hospital. She and I were partners in an interior design firm.

She surprised me by appearing at my door shortly after I got home, carrying in suitcases, groceries, and things I might need. Kathy was so helpful and we worked well together. Then my daughter and granddaughters arrived for the weekend.

I think you will need some help until you are able to exit the immobilizer. Then....another idea is there are rehab facilities where folks without in-home assistance can stay much longer than normal.

You are already working to build up skills on your prosthetic.......that's great. I hope to see your name at the top of my morning contact list whenever you need anything. You are certainly an encouraging individual and it has been my pleasure to connect with you.

May you have happiness and the causes of happiness.
Chris
