My Childhood Friend Killed His Sister

I had a best friend, let's call him S, from the 2nd to 5th grade. We were super close

and pretty much were our only friends. I have really good memories with him from 2nd to 4th

grade, but it all went crumbling down when 5th grade came along. I was being abused

at home, and my mental health worsened over the years and eventually I could not escape

it even at school. Obviously all the teachers and my peers noticed this sudden change in

me, and I was very vocal to S about how I wanted to die, and general depression

and suicidal thoughts. This brought out a side of my friend that I never knew existed.

He became extremely mean to me and bullied me when it came to my mental health, never to my face,
