Last week a news story sent a shiver down my spine. During the inquest into the death of 15-year-old Tallulah Wilson, her mum called for action against the "toxic digital world" that made the last months of her daughter's life hell. It's a feeling I share.

On the evening of Tuesday 17 September 2013, my 14-year-old daughter Izzy Dix took her own life. For a period of almost two years Izzy was bullied. She was tormented at school, in the local community and online. We spoke openly about this, I contacted the school on many occasions, and I was trying my best every day to help and support her through it. The worst of the online bullying took place on a website called Ask.fm.
