Supervisor replied to what I feel like at least 20 emails from student asking questions about the assignment over the weekend (she cced me everthing) and still hasn't gone mad! She's a saint.
Maybe next time if she asks me again 'are you happy' I could actually tell her 'yeah I am only able to sleep for an average of six hours per day what do you think' (
(well she doesn't deserve that. meeting with her usually feels nice. I'd be calmed in the end when we get to that part of exchanging best wishes.)
