To be honest, for this one I would say "Mom, I've been working hard all day and I'm wiped out. Can you please get some help for me?"
my dad used to be like this all of the time. it was awful.
This usually works because then usually one of two things happens: you get the task off your back, or you get help, which may make the task faster and get done quicker. Either way, you can get back to resting. Even if it didn't work, at least you were respectful of your parents and not hard on yourself after a hard day's work. Getting rest when you need it is biblical, peeps. Overexerting yourself too much isn't healthy.
