I've only watched one episode, and I had issues with some of that episode (specifically the use of the phrase "psuedoseizures" on live TV), however, the thing that is really irritating me is the phrase
"Suicide is a trend. A trend" in the opening scenes of the episodes. It's stated by a teenager, and whilst I get that's her opinion, it's a freaking dangerous one to be shared so publicly by Channel 4 in a program that is supposed to be educating the public about mental health in the UK.
