What I'm saying is that I have chronic fatigue+pain and I'd be on a solid 9 out of 10 on the pain scale for the whole of Monday. I would be genuinely worried that I'd pass out from pain at some point. I cannot even process what it would do to me, to try to also come in on Tuesday. That's why I completely misjudged how difficult this would be for her, even though I was aware that she's healthy. I just assumed even healthy people would run out of steam, if they're doing things multiple days in a row.
If your levels of health allow you to work that job, then check your goddamn privilege honestly good for you.
