ReachOut WorryTime
Everyone has worries pop into their head from time to time, but sometimes they won’t go away and start to impact your everyday life. ReachOut WorryTime interrupts this repetitive thinking by setting aside your worries until later, so you don’t get caught up in them and can get on with your day. This means you can deal with worries once a day, rather than carrying them around with you 24/7. Produced in consultation with the Centre for Clinical Interventions, ReachOut WorryTime is based on cognitive behavioural techniques that are used by health and wellbeing practitioners to assist people with anxiety and stress.
