I hung up on my mom yesterday while we were having a fight and I told her "F you."
What did you mom do to enrage you to that degree?
The fight was all her fault and she was being mean to me.
Being upset at a parent for being mean to you is understandable but you should try to show more respect rather than cursing at them. Wanting to leave the conversation makes perfect sense to me but try to leave out the foul language in the future to be more respectful.
I'm still mad and you don't know what my mom did to me.
You probably have valid reasons for being upset, but using foul and disrespectful language towards your mom only fuels the situation negatively. Leaving the discussion wasn't a bad idea, but in the future you should do it a bit more calmly and with more maturity.
