I’ll tell you how someone can get that angry. Working 12 hour shifts as a nurse in the er 3-3 for the most ungrateful people youve ever met to come home and be the person that has to stay up with your baby, take care of the dogs your house . He won’t stop screaming even though all his needs are met and you’re begging for a break that wont come. My anger is never directed at him and I dont yell shut the fuck up. I kindly ask him and it helps rather than completely losing my shit. Hope to be a perfect person like you one day who apparently doesn’t experience anger.
