Glad to hear you're doing better.

I wouldn't think that you're ever pissed for no reason - probably more for an unknown reason - one that hasn't seen the daylight of conscience. Could be the tiniest change in the chemistry of your body, could be something getting in the way of your metabolism, an organ working overtime, even a bad dream that you don't really remember... Or a bunch of these working together.

I'm unfortunately in the process of evicting a roommate who seems to get pissed for no reason at all...
