There is no reason why this woman needs to bombard you with so many emails whenever she gets upset... 40 emails is quite excessive. I agree that it's borderline harassment. I would suggest that you send her a message about reducing the amount of emails that she sends to you.. You need to express yourself to her that whenever she sends you this many emails you become overwhelmed by the amount that she throws at you. If she doesn't care or respects this request... then you may need to start thinking about blocking her... add her account as spam so Gmail can start putting all of her emails in the spam folder.
