Your post reminds me of a South Park episode where Cartman gets diagnosed with Tourettes,so he can yell obscene words without getting in trouble... Honestly,you should be more worried about your manners than moods. There's NO excuse for being mean to random people, if you're seeing a therapist, I suggest rather talking about how you enjoy mistreating your peers.Yes, I've been mean to others, but felt bad afterward, and apologized. I never found it funny,and dont understand why you continue to laugh about it
