Anyone else have a hard time with their loved ones not fully understanding what's going on with them?

My husband has been super supportive, don't get me wrong; but at the same time, I can tell that, sometimes, he's forcing himself to be nice or "tolerating" my telling him that I need to rest. I feel like he may think that I'm making up symptoms to get out of doing things around the house or to get out of working more hours, etc. Like right now... I'm finding myself feeling a dire need to lay down for a little while, but I know he's going to be upset with me when he comes home and finds that I haven't cleaned the house yet (although I did spend four hours cooking for our party tomorrow).

I already feel guilty because I'm not able to support our household as much as I should be able to, between losing my job and working for so much less pay now, but then on top of that I have this lack of energy as well; I'm sure I look very lazy to him, and that's frustrating because we've had issues with that before, but now it's for different reasons and I don't know how to make him understand that.
