Julia is 13. She spends hours locked in her room, on Discord. Slowly, the sweet and communicative girl everyone knew disappears - replaced by someone aggressive, isolated, and emotionally volatile."Typical teenage behavior," her father thought.He was wrong.Behind that closed door, his daughter had been pulled into something far darker than he could have imagined.It Happened to My Daughter is a true story - told under a pseudonym - of a father who watched helplessly as his daughter became entangled in toxic online communities, began self-harming, simulated a hanging, and went through repeated hospitalizations and psychiatric treatment.This is a book about the invisible dangers hiding inside the screens our children carry everywhere. About the silent, calculated power social media holds over teenage minds. And about what happens when a parent finally stops dismissing the signs.But it is also something else: a story of a family that found its way back. Of bonds rebuilt, affection rediscovered, and the possibility of starting over - even after the worst.
