Repeat after me: I will never attempt to sort out issues with my boss when I am PMS-ing, or am otherwise severeley stressed. I will wait for a good time, when I can think more rationally, and keep my mouth from blurting out things that should not be blurted out even under severe distress. This is a mantra everyone should follow religiously. Trust me - I have just learnt this from a shakey personal experience :(
