I think this is a great description of that feeling, and one I share. It's led me to the thought that at the moment, I just won't be able to do something in the morning I'm not intrinsically motivated to do more than just continue sleeping. Extrinsic rewards don't seem to do that, but meeting friends for a sporadic event like coffee early in the morning, or a hiking trip do. I think you've solved this in a novel way with your caregiver.
