This episode begins inauspiciously, as son Josh turns eighteen. Outgoing, football-mad and usually the loudest, wildest joker in the house, Josh has always thrived on attention. So when he shows no interest in celebrating such a milestone, alarm bells begin to ring. When Noel asks what he wants to do for his birthday, Josh's answer is stark: nothing.

This episode of 22 Kids & Counting is unlike any before it. Filmed over nine months with Josh's full consent, and made with the guidance of mental health professionals, it tells a story Josh never expected to share – but one he chose to tell so others might recognise themselves and seek help too. Moving, heartbreaking and ultimately uplifting, it's an episode that won't be forgotten.
