Speaking to Good Morning America, 16-year-old Toni said following her father's tragic death, it's inspired her to "change the conversation" around stigmas surrounding addiction and mental health.
Toni and her brother Christopher have launched a new initiative, called 'Stop the Stigma', where they intend to educate young people about substance abuse disorder through a program that will be launched in schools across America.
The Stop the Stigma website has recently launched, where in an open letter Toni wrote:
In the open letter, Toni explains that her late father began to experiment with drugs at the age of 14 which onset a panic disorder, but because he never told anyone, he suffered alone.
She then goes on to explain that Chris learned from his mistakes and passed those lessons onto his kids.

It's pretty heavy to read, but such an important subject to talk about.
