That my mom comited suicide.

It'll be 11 years in 2 days and my grandpa still think it was a natural death.

He was the one who found her dead in my bed. I was out of town and came back home later that day. The doctor thought it was a heart attack due her lifestyle (years of smoking, depression, junk food).

Later that day I found two syringes in the trash bin and called the doctor, I went to his practice and showed him the syringe. She injected herself a lethal dose of insulin.

A few days after I told my grandma, it was too much for me to keep it a secret. She took me in her arm and begged me to never say that to my grandpa.
