Is AUTHOR wrong in the post ? POST : 

A background: my parents have been in a long term relationship since I was 11, my dad lives in our native country and i had to move back in with my mom and sister here in the US.
I hold a lot of resentment towards my dad because he was mostly absent and when he was around he would only “discipline” me. some of the ways he would punish me:he caught me eating his chocolates, so he sat me down and started shoving chocolate, after chocolate in my mouth until I started chocking. Other times he would hit my sister in front of me until I started crying and apologizing for whatever minor thing I did. Both my parents were extremely verbally abusive. 
Fast forward to 2019.My dad is visiting and on Tuesday last week, my mom berated me for not being as good as my sister, I called the Suicide hotline because it really got to me. The next morning I woke up my son early to study, he had to retake a test after getting a 0. My son didn’t want to study, after lots of pleading, I lost my temper and yelled “sit down and study” my parents then started yelling across the house telling me to shut up which I ignored, when we finished studying, he went to get ready. I went into the kitchen and told both my parents firmly that They needed to stop saying things like that in front of my son, my dad told me that I shouldn’t talk to my son like that, this struck a nerve because of the night before, I told him neither of them even showed respect to me even as a child, I reminded them of how my mom used to keep a belt by her side when we studied, and how she would hit me for giving the wrong answers, and that I would never do that to my son, yelling wont hurt him. We had a lot of back and forward until my dad just told me to leave cause he didn’t have time for this, and I yelled at him and told him I want to talk, I’m done with you guys always telling me I’m a fuck up, you guys are terrible parents and I really only want to have what my friends have with their parents” he rolled his eyes and started laughing at me. I took my son(who by this point was in the kitchen hugging me, telling me it was ok) and didn’t come back home until my SO was out of work. I didn’t talk to my dad after that, he went back to our country and my mom has only talked to me to let me know how much of a bitch I am for not saying goodbye to my dad, and that I should be grateful to my dad as he has worked so hard to give us a what we have. and that she wasn’t kicking me out because she didn’t want my son to suffer but she was done with me too. 

So AITA for my outburst and for not saying goodbye??
