Pooping is supposed to be pleasurable, so I don't connect it with anger or depression. So, I soil myself whenever I have a good poop on the way and have the time and opportunity to enjoy it, and that usually implies that I'm in a good mood. However, if I happen to not be in the best of moods before I poop, the eroticism of having that in my diaper or briefs soon makes me forget whatever I was irritated about and I concentrate on the loveliness of what I've done and prepare to enjoy it to the fullest. Nothing like having some poop time to change a lackluster day into a good one.
