Don't worry about whether he is noticing anything you do. For one thing, it's nto the point. And for another, he wouldn't know if he was anyway! But he IS seeing it.
Worrying about what other people are thinking is a bit of a pickle. At some point, I think you have to let go of that. But, in general, they are probably noticing less than you are afraid they are. Everyone has their own lives to worry about, and most of them are not paying nearly as much attention to the details of yours as you are afraid they are! And the ones that are.... well, if that's what keeps them happy, what can you do?
That water heater thing really gets me.... so controlling!
You are sounding better, bit by bit! I think you are feeling it, too!
