Shit science
It's amazing the propaganda they're allowed to spout these days.

A more truthful poster would read:

Depressed? Suffer from a severe chemical imbalance which requires medication to stabilize? Fear not, because listening to lots of Bollocks will make you feel better. Fact.

Grr.

Edit - I do hope it's routine stuff and not a blip on the radar CHCB.
