What should I do about my boyfriend’s behavior?

r/

My boyfriend(22M) and I(21F) have been dating for nine months. He often drinks alcohol gets too drunk and then takes it out on me non physically.

A few days ago, I hit my head on the pavement after taking a fall. This is right in the middle of finals, whereas I am supposed to be graduating this semester. I finally decide to go to the doctor today because I have a headache and my vision is a little blurry. I go to the school doctor, which then tells me to go to the ER because symptoms are worrisome. The school doctor doesn’t let me leave the building without somebody coming to get me. Obviously, I call my boyfriend who lives with me, to come and get me. The only problem with that is that he was blacked out drunk so I had to call my other friend. This friend gets my boyfriend in his car and takes us to the hospital. All three of us are waiting in the waiting room and my boyfriend leaves. Apparently he went in the parking lot and threw up a bunch. I’m waiting to get a CT scan and cannot deal with him. After I get my CT scan done and everything he gets back inside my other friend at this point has to leave, leaving me alone with my boyfriend. While we’re waiting, he starts getting aggressive calling me a beach, saying that this is a waste of his time, and generally just being rude to me. At this point I’m frustrated because he’s asking me the same questions over and over and my headache is not going away. I tell him to leave if he’s going to do that, but he says “no frick you I’m not gonna do that.” We finally get discharged, and on the way back he’s asking me the same questions again. When we get out of the Uber, I walk across the street to our apartment, and he just stays there. He leaves to go drink with his fraternity friends. And now I’m here alone at home with a huge headache and a concussion.
The thing about this is that things like this I have happened before. I hit my head because I was trying to pick him off of the floor after he was blacked out and he left the apartment. He’s called me weak when I got diagnosed with anxiety and depression because he doesn’t believe in it. I’m just starting to hate him. I don’t want to. But it’s hard when somebody treats you like this, especially if you love them, and especially when they say they love you.
I’m just tired and my head hurts. I don’t know what to do. He’s just hurt me so much and it’s obvious he doesn’t care about me. I guess I can’t beg him to love me, but I do still love him. When he’s sober, he treats me like a queen but when he’s drunk, his behavior is inexcusable.
Sorry, if there any typos, I have a concussion.

TL;DR: boyfriend was rude the whole time during my ER trip.
