Is AUTHOR wrong in the post ? POST : Hi Reddit, on mobile sorry for formatting. Long time lurker, first time poster to this sub. Sorry for the wall of text, backstory is needed.

So like the title says, my father and I got into a huge fight a couple months back. Things have always been rocky between us ever since I was around 11 or 12, because he’s always had terrible anger issues and I started dealing with depression and anxiety at a young age because of it. I started letting my grades slip and started not wanting to do any kind of work in school and at that point my father thought that I was a complete failure and would be no more than a "lying, conniving fox". Thing is, because of his anger, I would lie and hide things from him. Wouldn't any normal child do the same? Knowing that your parent would go off on you. Things got worse and worse to the point that he started beating me. I remember very vividly one time he grabbed me by my hair, was dragging me around the floor and threw me against the wall. 

Fast forward to fight. My dad had gotten mad when he picked up my daughter from pre-k and thought he saw my ex's name on the box where it's signed who dropped her off in the morning. (Whole other story, but he's not a good person and it's why he's an ex now) I know for a fact that I dropped her off. He insisted he saw another name. I started getting upset because I KNEW I was innocent, and started yelling at him and letting out how he doesn't trust me from back then and that I have issues because of it, and that I would be seeing a therapist soon because of him. He yelled back at me and was saying "bullshit, there's nothing wrong with you. A therapist won't tell you crap" at this point I'm fuming and am so upset I'm bawling, and start telling my daughter to get in the car and we're leaving. My dad then says "don't you take it out on her, she didn't do anything wrong" to which I said "why? You beat me whenever you were mad at me. She's my daughter, I can discipline her the way I want" (I would never treat her the way he did, I was just so angry) and he said "because you deserved it. You did that shit on your own. You lay a hand on her, I'll call CPS, same way you did on me" (I did call once cause I was bleeding and bruised so bad, but they never did anything) at this point I don't even say anything and leave. The last text I have from him after that fight was Jan. 10. I haven't not spoken to him since, have not seen him and don't go around him anymore. 
When I did see my therapist, I told her everything that happened with my father and how it has affected me in that I am terrified of confrontation and someone being upset or mad with me. She ended up diagnosing me with PTSD, anxiety and severe depression. I told my sister who told my mom, who I know told my dad. But he still hasn't said anything to me. I ended up getting a service dog and she's been wonderful, but now I'm starting to doubt myself.

So Reddit, AITA?
