AITA for telling my younger sister that I don’t believe she is actually a lesbian?

The air was thick with emotion as Sarah, 26, finally bared her soul to her family, revealing she’s a lesbian after years of silence. Picture a cozy living room, warm with lamplight, where hugs and tears sealed a long-awaited moment of acceptance. But the glow of that milestone barely had time to settle before her younger sister, Emma, 24, swept in with a theatrical flourish, declaring she, too, was a lesbian—known “way before” Sarah.

The sting of that announcement cut deep. For Sarah, who’d spent her life overshadowed by Emma’s narcissistic personality disorder (NPD) and constant need for attention, this felt like another jab at her moment. Was Emma’s claim genuine, or just another ploy to steal the spotlight? The Reddit community weighed in, and the drama unfolded with raw, relatable tension.

‘AITA for telling my younger sister that I don’t believe she is actually a lesbian?’


Emma’s dramatic coming out, timed suspiciously after Sarah’s, screams of attention-seeking behavior, a hallmark of narcissistic personality disorder. As Dr. Ramani Durvasula, a clinical psychologist specializing in NPD, notes in her book Should I Stay or Should I Go?, “People with NPD often crave admiration and may co-opt others’ moments to redirect focus onto themselves” (source: publicly available excerpts).

Emma’s claim of knowing her identity “way before” Sarah feels like a calculated move to diminish her sister’s milestone. This situation highlights a broader issue: navigating family dynamics when mental health conditions amplify competition. Studies suggest NPD affects about 1% of the population, but its ripple effects on families can be profound (American Psychiatric Association, 2013,source).

Sarah’s frustration stems from years of being sidelined, a common experience for siblings of those with NPD, who often face enabling parents prioritizing the disordered child. Dr. Durvasula advises setting boundaries: “You can’t change the narcissist, but you can protect your emotional space.” Sarah’s outburst, while raw, was a reclaiming of her voice. She could benefit from low-contact strategies or therapy to process her resentment.

For Emma, therapy is crucial, but parental enabling may hinder progress. Open communication, perhaps through family counseling, could help Sarah’s parents see the imbalance. Ultimately, Sarah deserves to prioritize her truth. Acknowledging Emma’s possible identity while setting firm boundaries—like calmly refusing to engage in her theatrics—could help Sarah reclaim her narrative without guilt.

Take a look at the comments from fellow users:

Reddit’s hive mind didn’t hold back, and their takes are as candid as a late-night chat with friends. From calling out Emma’s suspicious timing to sympathizing with Sarah’s lifelong struggle, the comments paint a vivid picture.
