Is OTHER wrong in the post ? POST : I'm on mobile so sorry for formatting

So to start, I'm in highschool, this is my junior year and I just got off a call with my girlfriend of about a year. We didn't break up but we did fight. Here's the run down.

It's late right now and I have to study for an anatomy test tomorrow. Enter GF. GF wants to call for the night and I tell her from the start, I have to study for this test, I have a coffee and a lot to do so I need to make this quick. She then tells me to pour out the coffee and go to bed because I always get mad when I'm not well rested (and she's right. I get a bit snappy), and that it's going to make her feel bad because there's nothing she could do about it. I say it doesn't matter whether or not I'm well rested and no matter what there's nothing she could say to get me to change my mind.

We go around in circles, her telling me to stop and go to bed, me telling her firmly and calmly something along the lines of "I know what I'm doing is selfish and irresponsible but it needs to be done. I need to get off and do this paper. I love you, goodnight,".

Again we go in circles as she will not let this go. After three or more time of this I say as firmly as I can "Look. It wouldn't matter if I was well rested tomorrow, it wouldn't excuse the fact I don't know what the fuck a sclera is."

I will admit. I probably should have said it in a less tense tone but I didn't yell at her. She of course goes silent and says that she hates being yelled at. I appologise and she's just mad at me. I tell her I love her and I hope she has a good night. She responds with "bye". I know that's a bad sign but I know there's nothing I could do, so I hung up.

TLDR; stayed up late studying, gf wanted me to sleep, I refused, we go in circles, I shut it down, she gets mad.

So, AITA?
