Note the name of the source...the UK Government's Department for Health and Social Care. Guido has the whole document embedded HERE, just as well because Scribd has already removed it, presumably on request from some government employee after having read Order-Order!
Staff at the Department have been issued with a 'Toolkit' on to help them "understand the impact which change and uncertainty is having on the way you feel". Oh dear. "Staff are then instructed how to “take back control” and shut those bad Brexit thoughts out. The key is to "challenge your inner critic” and “kill your Automated Negative Thoughts (ANTS)"". FFS.
