AITA for this situation with my mother?
I need advice. This is a new reddit account since I've never had one before, but I have listened to loads of podcasts abt AITA subreddit. I'm from the U.S but go to school in the UK (third year), I'm currently on vacation with my family (Mom and younger brother) in Denmark. I've been super stressed out this trip because it's the middle of the month and I haven't paid my rent for my student accommodation, because my Mom refused to pay half of it because she's in a fight with my Dad (they're divorced) and my Dad has basically blown me off but supposedly he will eventually pay it, also I just finished exams but I still have an essay to finish writing that I haven't had time for. Also, being around my Mom is hard because she is criticising, easily irritable, makes comments about my weight, etc. We've always had a rough relationship, but she doesn't know that because I never complain to her. All of my siblings have problems with her because she is so intense, scary, angry at times. This all comes to a head tonight at our Airbnb because I made myself a salad for dinner and didn't make her one. She screamed at me and I apologised and made her one along with the roast veggies I made for all of us. I presented it to her as a peace offering and basically she has said she is disowning me and that I'm deeply selfish and that there's something wrong with me, to the point I was crying.
Why I might be the AH--I probably should've just asked her if she wanted one but it didn't occur to me since we've been fending for ourselves and also she saw me make the salad and didn't say anything / she was preheating the oven for some pasta dish for herself. Also, she does pay for my rent/ is my mother/ provides for me etc so I should be grateful. She sees this as a big betrayal. She also cited me being grumpy on this trip as me being ungrateful etc. It's hard for me to be super chipper when she's constantly critiquing me, I have to plan everything, arrange everything, etc because she doesn't have a clue. EX: She screamed at me at the train station because I was walking towards our train, b/c she thought it was in the other direction. It wasn't. Also, I texted my other brother abt the issue and he basically told me I should just be as nice as possible. I guess I'm out of practice since I've been away at school.
Why I don't think I'm the AH--My brother who I texted basically was like ignore her and she'll be over it by tomorrow, which tracks, as she's verbally disowned me a million times and same to him, always over minor issues. Also, I don't think me not thinking abt making her dinner constitutes a personality flaw, but it was inconsiderate. I basically want reassurance that I'm not being evil???
This sucks because I was going to beg her to cover my rent since my dad hasn't and that seems like a no-go especially since she basically told me to never ask for anything from her ever again since I'm so selfish.
