Sorry about this post being kind of long, but please read anyways so I can get help.

This past weekend, my daughter (14F) pitched a huge fit because she was very upset over something. She was screaming, crying, and cursing at me, which lead to me (40F) being in tears and threatening to call the police on her.

There was a dance at her school on Tuesday night, and she has a concert she will be going to over the summer, so I eventually told her that she needed to stop, or she would not go to her school dance on Tuesday night, and she would not go to the concert. For some reason, she has always had a problem with me threatening her to not go to an upcoming concert because it makes her, "uncomfortable", so she started whining at me for bringing it up.

I told her that her concerts were a privilege, that we were allowed to threaten it, and that the only thing we had to give her is food, water, and shelter. This answer didn't satisfy her, and she went to her room. She then came out a little bit later, claiming to be sick and throwing up from being upset about me threatening the concert. I comforted her and helped her the best I could, then she went back to sleep before waking up and claiming to still feel sick. I started getting really worried about her and actually even apologized for threatening the concert.

Eventually, after she had already showered for school and claimed to throw up again in the bathroom, I started getting suspicious of her and thinking that she was just manipulating me into staying home from school. She claimed that she didn't need to go to the doctor for a doctor's note, that I could just let her stay home with a written note, and that she was worried that she would continue dry heaving at school. The reason why this made me think she was manipulating me is because she doesn't usually fight going to the doctor's office when I let her stay home for being sick.

I told her that if she went to school acting like something bad happened to her at home, she would not go to that concert. She started going off on me for threatening the concert again after she apologized, and I told her that she was also threatening me by talking about going to school and acting like something is wrong with her.

She ended up going to school because I would not let her stay home unless she went to the doctor's, which she refused, and when she got home, she continued to claim she still felt really sick. I was tired and laying in one of the bedroom's, and I just told her to think about other things. At this point, I was pretty sure that she was just pretending to be sick to manipulate me into feeling bad for threatening her. I think that because it never happens to her just because she is upset with me and uncomfortable over something. The fact that she was better as soon as I stopped comforting her and responding to her claims with empathy further proves it.

She tried to continue arguing with me, but I told her that she was bothering me, and told her to go on. She went to her room and I could hear her screaming and crying from being upset, but I ignored her. She can't just act like a psycho and scream at the top of her lungs while cursing and play victim when she recieves consequences for it. Hours past and I fell asleep as well, and when I woke up, she was still in her room. When I got up from the bed and went to sit in the living room, I could hear her upset in her room some more, but I just tuned it out because I was done with her.

At 4 in the morning, she came out of her room, perfectly fine, not sick, and talked to me. We never spoke about earlier that day and the night before, and we moved on, but I feel kind of bad for leaving her alone for all those hours. She was being manipulative and a brat, but I still wish I had checked on her after all that time, considering she fell asleep at 4 pm and didn't come out of her room until 4 am, so I want to know what y'all think.

AITA for leaving my daughter alone in her room crying for hours without checking on her, or did I do the right thing by ignoring her tantrum?
