Input: Hi all, long time lurker without an account until now. 

About a month and a half ago, my mom (62F) and I (28F) had a \~2 hr long fight over the phone. It started with her accusing me of making up stories to try to make her look and feel bad---I showed her written and picture proof of the event I was talking about (I was an avid journaler during the time that we were fighting about), and told her I was really not okay with being called a liar when I obviously wasn't. The fight then meandered through a bunch of other issues, and ended with her demanding examples of her being overly critical, which I provided, easily, as she is a textbook tiger mother. She reacted by straight up calling me a liar ("you know what, you are such a liar") and I told her "f you" and hung up on her.  

We are neither a fighting family nor a swearing family (my sister and I used to get in trouble for saying "that sucks") so this was a REALLY BIG DEAL. My sister (32F) told me I was way out of line and need to apologize. My dad also said that I should apologize because she's the only mother I'll ever have.  I'm was/am still stuck on how my own mother called me a liar (twice) because she didn't want to admit that she did some irrational/imperfect things. I told my sister that I wasn't okay with just lying down and taking whatever verbal and emotional abuse our mom dishes out to us anymore, but my sister said that by telling her to go f herself I was abusing her.  

My sister also brought up the point that our mom definitely has some mental health issues and she can't help herself so we should be understanding. She is undiagnosed because she's resistant to going to see anyone, but depression is definitely on the table. And she had just been really upset by something my dad did (long story) so she was probably feeling particularly fragile at the moment. So maybe I was too harsh and should've apologized. My mom and I are both extremely stubborn (apple, tree) so we haven't talked at all since except that I texted her happy birthday last month (not talking isn't atypical though, I never call because of the whole overly critical thing). AITA for not apologizing?  

tl;dr: my mom was upset about something, we had a fight where called me a liar twice when I wasn't. I told her f you and hung up, still haven't apologized despite sister and dad insisting, AITA

saying f you to my mom and hanging up during a fight when she was upset
