Problem with aunt

Hello. So to give some context to this, i have an aunt kber menni b 13 ans, that has been weird and had secret animosity since i was a child. When i hit 13 yo, she had a 2 y.o kid w bghat tsktha b my laptop, i used to work on a presentation fih so i respectfully told her that i can’t (+ her baby broke her laptop). She then left our house angry and talked shit about me to the family allegedly. Since then she always excluded me or gave more compliments to my older sis (it was always the case but she didn’t hide it anymore). Ana i resented her deep inside for 10 years but i kept being very fucking respectful and mswaba. When i hit 22 y.o she « changed » maaya. We started talking a lot whenever she came, she bought me cute gifts for my bdays and such, so in my heart i forgave her for her behavior maaya when i was a kid. Until yesterday, where she came to our house raging because of my grandma. Ana this past week ive been in a very dark place mentally, but i got better yesterday, although i didn’t eat so i was feeling dizzy w dissociative chwia. So sllemt 3la her kids and i didn’t see her in my vision so i completely forgot to greet her. W ana nbda nsme3ha ta tghwet « im your aunt why tf wouldn’t u greet me, next time ill tell my child to do the same to u », i still kept it respectful even tho she talked to me in a condescending way even tho im 24. Brrdtha about grandma and i kept giving her advice. She then talked again about the greeting stuff in an agressive accusatory tone w makhellatnich ndaf3 ela rassi or even talk. She was saying f islam i shouldn’t care if u had a bad day or a bad week (cuz i told her that if someone doesn’t greet u first thoughts u should have hia he probably isn’t feeling well or forgot or or which was my case) but she was like thats bullshit. Ana since im already feeling down for a while i started crying w mchit l toilettes hit she completely unleashed her anger at me w madrt liha walou. Tb3atni l toilettes, she cornered me with the wall, and kept saying im not respectful etc.. alors que im the most respectful and calm one f the family. Dik sa3at i lost it. I have gastritis and since i didn’t eat anything te7t and i started convulsing. And she kept saying « awili madert liha walou hadchi kamel bsbab slam » and mom jerrat 3liha. Im still shaken up by what happened. My only issue here is why is she like that with me, cuz she has a history of this behavior maaya. My mom told me that she was a degenerate teen she didn’t study well and kept sneaking to drink with adult men. But still it doesn’t explain this behavior. Im sorry this is way too long
