AITA for yelling at my SIL and making her cry when she kept offering me her milk?
A family dinner meant to bring loved ones together turned painful for OP, who lives with lupus and its visible rashes. When sister-in-law Kat repeatedly offered her breastmilk as a “cure” for OP’s condition, ignoring polite refusals and dismissing it as mere acne, tensions boiled over into a heated argument that left Kat in tears and OP asked to leave by their parents.
Was OP wrong to lose their temper at Kat’s insistence? Or did Kat and the family lack the empathy needed for OP’s serious condition? Let’s dive into this emotional story and the vibrant reactions from an online community.

OP loses their temper as Kat continues:



OP’s situation reflects the conflict between personal boundaries and family insensitivity, particularly regarding a chronic condition like lupus. Kat crossed a line by publicly commenting on OP’s appearance and pushing an unscientific “solution” despite polite refusals. The family’s failure to support OP, and their skepticism about her diagnosis, exacerbated her sense of isolation.
Dr. Harriet Lerner notes, “Respect in relationships requires listening and accepting a ‘no’ without pushing further” (The Dance of Connection, 2001). Kat’s behavior, though possibly well-intentioned, became disrespectful when she ignored OP’s refusals and doubled down on breastmilk as a “miracle cure.” OP’s outburst, while harsh, stemmed from accumulated frustration over Kat’s insensitivity and the family’s dismissal.
Socially, lupus is a complex chronic illness, and those affected often face misunderstanding or minimization from others. Kat was wrong to publicly critique OP’s appearance and propose an unfounded remedy, especially in an environment where OP already felt unsupported. The family’s reaction—siding with Kat and asking OP to leave—further compounded the issue by failing to acknowledge OP’s condition.
OP should consider a private conversation with Kat to explain how her comments were hurtful and inappropriate, emphasizing that lupus requires medical management, not folk remedies. OP should also address the family’s skepticism, highlighting how their doubt affects her mental health. If the family remains dismissive, OP might consider limiting contact to protect herself. Joining lupus support groups could provide OP with empathy and tools to navigate similar situations.
