My sister-in-law is a complete bitch and has upset me so much I can't focus on anything but how angry and upset I am. I shouldn't let her bother me because we hardly know one another and have only met in person a few times. It feels so unfair that she was able to be so nasty and say such horrible things and not one person has asked if I'm okay. She judged me without knowing me, and at every turn I have tried to understand her, but she seems to simply not want to like me. She said if my husband won't talk to her there's no point in her having a relationship with me, amidst throwing insults at me about us. There was no need for any of it and now I've just got it all stick in my head, all because she's a 39 year old child with no emotional intelligence or ability to regulate. She knows literally nothing about me beyond my name and that I married her brother. She has hurt me so much and she has no clue because she threw out her insults and left the group chat. I think I hate her.
