agreed. the edit, the fact that we don’t know these people in real life aside, it’s pretty clear from my pov that she’s projecting and repressing alllll that stuff about her childhood and her past and current relationship dynamic with her mom and siblings–she’s the black sheep, or sees herself that way. the black sheep/victimhood narrative is the framework for how she sees the world and it will continue to result in toxic relationships until she does some work on herself. while tj, his mom and yash may not be fair to Kim and may actually be jerks, I can see them completely perplexed and exhausted by her big reactions to what they see as normal expectations.
from my personal experience, I would imagine that if she had a therapist, they may not be trauma-trained, particularly in cptsd which given the little we do know about her history and what she said, may be necessary (obvi this is a jump, on my part and I’m not qualified to diagnose but can speak based on the similarities I see in my experience versus hers). it can take years to understand how childhood trauma may shape your interactions with anyone, not just family, when you’re an adult and even moreso difficult to acknowledge to yourself that you’re not “over it.”
