AITA for ignoring my sister's plea?

“I ignored one text… and I still regret it every day. ” I was halfway through my shift when my

when my phone buzzed. A message from my little sister. “Please don’t ignore this.

I need you.” I stared I stared at it for a second. Then I locked my phone and went back to work.

Thirty minutes later, I checked my phone again. I had twelve missed calls.

My hands started shaking. The last message was from my mom. “If you love your

sister, come now.” She was in the emergency room. Pills on the floor.

A note on her phone — not to my parents… But to me. She survived. But she won’t look

at me anymore. Every time my phone buzzes now, my heart stops for a second.
