I've never really gotten in an argument outside of my family big enough to start throwing personal insults, but ALWAYS with my older sister. It's not entirely my fault though. She gets mad at me about the stupidest **** which really sets me off, and I go straight for the jugular each time by telling her how she failed to launch/has no friends/acts like she's hot **** when she does have friends/is going nowhere in life. She doesn't get visibly upset about it but I feel bad after since she's been battling anxiety the past year and a half.
But then she pisses me off again, makes me not feel so bad, and the cycle starts again
