Pain
When your sick mama tries to do a task she's filled with pain!
Sick people shouldn't have to do things, of course they're in pain. You shouldn't let your mama do anything if she's in pain, do it for her!

Your mama's pain is too (つう) much for her to handle, so now you have to do all of her tasks too.
You finish doing your tasks and hers too, and you ask her, "How is the pain now, Mama?" "THE PAIN IS TOO MUCH!" she cries. Oh mama.
