I’ve struggled for a short while, due to breaking my collar bone, though I was able to cheat, as my right hand worked but was initally immobilized. Having a very understanding partner helped me, though I’m still using my left arm almost as my domiant arm now (shoulder looks to be frozen), if anything too much, as I need to use the damaged side more.. Ablutions were a struggle to start with but managable after a while, electric toothbrush was a godsend, silicon scourer meant I could wash my working hand, while the scourer was held loosely by the other one. Lots of veg comes pre-chopped, though I wouldn’t buy this at any other time, or a food processor can chop stuff up easily.
Oh and my car battery died from non use, maybe disconnect it, or run the car regualrly to keep the battery topped up.
..trying to think of anything else..
