AITAH for telling my mom she does nothing with her life after she compared me to Hitler

Sorry this was longer than I anticipating it would be 😅 You can skip to the last paragraph if you don't care.

I am 17 and my mom is 37. We are usually pretty close and I love her, but recently I have found myself resenting her and arguing with her more and more.

My mom is a stay at home mom while my dad works out the house. As the oldest sister, I am basically a second mom to my five siblings. On top of that, I am an online college student taking summer courses and I volunteer 32 hours a week at a disability resource center for kids. This tkes up a hefty amount of time, but my mother still expects me to handle the cooking, cleaning, nd tutoring for all of my siblings. I cook everyone breakfast and dinner every day of the week and sweep and mop the house multiple times a day.

I feel incredibly overworked and burnt out. Whenever I try to voice my feelings my mom shuts me down, tells me I am spoiled, and claims I just sit on my phone all day. If she were helping and genuinely needed my assistance, I would understand. But most of the time she just sleeps, watches TV, and occasionally cleans. I love helping people but I do not get any appreciation or acknowledgment from her and just that goes a long way for me. I never get a please or a thank you. Instead, she constantly tells me I never do anything and calls me lazy because the house is not clean 24/7, which is impossible with three kids ages 3-12 flipping the place upside down like 5 minutes after I finish cleaning it.

A bit ago, I finally snapped. I told her that I do all the work, that she just sleeps all day, nd that it is not fair for her to put her role as a mother onto me while she does nothing. She got furious and accused me of calling her a bad mom and gave me the silent treatment for a week. It ended with me crying for like an hour and apologizing to her saying I did not mean it just to get her to speak to me again. I know I went too far but I was so stressed.

Lately the biggest issues have been about my 3 year old brother. He is not potty trained but my mom insists he wear underwear instead of pull ups. I hve spent the last year constantly cleaning up accidents, cleaning up my brother, and washing his dirty underwear, which is exhausting and just gross. I cannot watch him every single second because of my classes. Yet, she blames me for him not being potty trained and says I am not trying hard enough. But I will admit I haven't been the most consistent with him.

Today, we got into another argument. She wanted my brother to test into an advanced studies academy, which is the same one I got into when I was 4. The test consists of IQ questions. For the past two weeks, I spent 30 minutes a day tutoring him. He has improved but I unfortunately didnt put enough time into him. We got the results today nd he ended up failing. When my mom saw the score, she yelled at me. She called me lazy, told me I am a horrible person, and said I never want to help anyone. She specifically comped me to Hitler, which took me wayyyy aback. I ended up snapping again and said something along the lines of atleast I actually do something with my life rather thn just sit around all day and watching tv. It was a word vomit as I was just throwing all my feelings at her for a good 2 minutes. I never directly called her a bad mom in this moment but my little speech did allude to it. When I was done, she just walked away. Now I feel like I went way too far and that she'll seriously never speak to me again.

All of this has built up, and I have honestly come to resent her. I did not want this to happen because I love her but idk what I'm supposed to do now. So yeah, AITAH?
