What's the worst lie you were told?

I had a girl catfish me for about 3 years, lying about having cancer and that her brother and his friends were abusing her, and the list goes on. She made profiles of about 6 people that all spoke to me, and after 3 years she died from cancer. I actually had to leave the classroom cause I started crying. Then I found out a week later that all the pictures were fake, and none of them existed 🙃
