When I first started the program, I had POTS and myositis, plus gastroparesis and peripheral neuropathy, and was bedridden, and needed help to bathe myself. Just visualize the DNRS practice, if that's all you can do. If you are saying the words and doing the motions in your imagination, then it still counts, until you can do more physically.
I don't remember mild exercise being part of the program except in the sense that moving one's body is good, especially if it's part of your "training zone." But you're definitely not supposed to push yourself with exertion, and you're definitely don't have to be able to exercise to be committed to the practice and see benefits. I certainly could not exercise, especially at first. Can you refresh my memory about
the exercise part?
The mindset changes are tough at first, no doubt. I used markers to write reminders and phrases and lists on papers that I taped all over one of my bedroom walls, where I could make myself read over them all day. That made it much easier to remember and remind me. Key phrases, ideas for grounding, adjectives I'd like to embody, memories for visualization, etc. I know it's so hard not to be jaded after dealing with an illness like Lyme that knocks us down and disappoints us repeatedly, but for DNRS to work, we really have to do our best to believe that it can help and give it a real chance. That's the only way our nervous systems can rewire and our systems in general can resume normal function. I'm rooting for you.
