Great app for breaking down how you feel

Had this app two days and already it’s had a positive impact on my life. I can check in, it’s almost like a therapist (my therapist recommended this app!) and it helps break down my overwhelmed emotions into coherent thoughts and helps stop spiralling into negativity.

Because it encourages you to take a step back, you end up taking tiny steps forward with your own emotions, without dumping them onto anyone else. Thank you for making this app.

Mobile Thought Diary

Having looked at CBT for a number of years the one area that has always stumped me has been the requirement for a thought diary. This app totally meets the requirements of the thought diary and allows me to challenge my NATs and has already made a significant change in my life.
