Neohdiver, I don't recall if you live alone or have someone with you. I was alone when I had my double mastectomy in 2013 (no recon). My kids came for a couple of days but that was all they could get away. I was very lucky in that the cancer was small and early so no rads or chemo. Hoping for this for you too!
My suggestion is make meals ahead store in serving sizes. Paper plates and plastic cups save a lot of extra work. Put things on the counter that you would normally have to reach up to get. You aren't going to be able to reach way up for a bit.
One of the most annoying things are the drains. I took an old zip up hoodie and cut off the hood and sleeves. Turn it inside out so the pockets are inside and slip the drains in them. Oh and satin type jammies make it a lot easier to get out of bed, they slide nicely.
I was driving in a week and doing most things on my own by 4-5 days. I had to, I live alone. I have always been a fast healer, I think being in ketosis helped a lot with the whole process.
Good luck to you, I'll keep you in my prayers!
