Please don't feel you need to apologize! I appreciate your taking the time to explain what you're dealing with. I really don't believe I can fully comprehend being in your shoes, but in trying to hear you, hopefully I can take a step in that direction. In hindsight, perhaps the suggestions I made are too labor-intensive given your current limits on energy? I wonder if there are any options near you for a meals-on-wheels type of program? I know these are usually for seniors, but I wonder if an exception would be made for a situation like yours?
When a relative of mine had surgery, she got offers from a neighbor to send over whatever she was cooking for herself, and that was sometimes helpful. If you happen to know anyone who enjoys cooking, you could possibly try to explain the challenge you are facing and see if they want to make a similar offer? Some people really do enjoy cooking! And they are often thrilled if someone is interested in enjoying the results. Some people even enjoy the challenge of cooking for someone with special dietary needs. And some folks can become real evangelists for 'healthy eating' and are happy to convince anyone and everyone, through their home-cooked meals, that a healthy diet can be enjoyable. It's kind of a long-shot that you or anyone you know would happen to be acquainted with someone like that, but that's another oddball idea I'll throw out there.
