I have a small lightweight bag, which I put things like pens, remote control, paper tablets glasses or whatever. This is easier to deal with so I take things in it to the bedroom or back to the kitchen or whatever, and you only have to think of that one bag of things , which you need to take things in, so that the infuriating effort of getting somewhere and finding you have left something that matters elsewhere. So I put a tape through the handles with a bit of velcro to then make the tape like a circle and could hold that with the crutch handle. Or again, talking about lightweight things you might be able to carry them in a bag over your shoulder. another useful thing I find is having a washing bag with a zip. Again to put bits and pieces in and then it is easier if you only have the bag to put somewhere rather than wretched little things falling to the ground where you cant reach them.
Also keep a little notebook and jot down things as you find them difficult. Then if you have a visitor you can ask them to do something for you. I often have difficulties opening jars etc and things like the oil bottles , and get cross with myself when I go to try and do them the next time and think I should have asked someone to do that for me. As regards meals, do you have a friend or neighbour who is a decent cook? I have done this for someone before. So I got a pound of minced steak and made up half into a good mince with onions, celery carrots etc, and the other half I made into a curry. Then split them up into indivdual portions and put them in the freezer. That way she just did a baked potato with the mince which reheated in the microwave, and she had that 2 minute bag of rice for the curry. If you had someone who could do something you like to go in the freezer that would make it easier for you and also tempt your appetite too. Then I think you might get the menus from chinese, piazza, and of course fish and chips! It may also be worth your while to check if a local church or community group do any lunches where either they might collect you and take you there or bring something to you. Hope you find something to enjoy
