Our picks

Addicted to Anxiety by Owen O'Kane

For people who feel anxiety is running their life. Psychotherapist Owen O'Kane argues that the behaviours and thought patterns that make us feel safe in the short term keep anxiety going, and sets out three steps: recognise your triggers, tackle the underlying habits, and plan for setbacks.

The Happiness Trap (2nd edition) by Russ Harris

For people caught up in worry, stress or painful thoughts. This updated second edition presents the techniques of Acceptance and Commitment Therapy (ACT), including clarifying your values, developing self-compassion and handling painful thoughts and feelings more effectively.

Women Who Think Too Much by Susan Nolen-Hoeksema

For women who go over the same thoughts again and again. Dr Susan Nolen-Hoeksema questions the assumption that constantly analysing our emotions is a good thing, and sets out how to break free of overthinking.

Overcoming Unwanted Intrusive Thoughts by Sally M. Winston and Martin N. Seif

For anyone troubled by unwanted, frightening or disturbing thoughts. Two anxiety specialists explain the different kinds of intrusive thoughts, why common ways of trying to get rid of them can backfire, and cognitive behavioural therapy (CBT) skills for coping with them.

Why Has Nobody Told Me This Before? by Julie Smith

For readers who want short sections they can turn to when needed. Clinical psychologist Dr Julie Smith covers managing anxiety, low mood, criticism and self-confidence in bite-sized entries with practical coping techniques.

Mindfulness by Mark Williams and Danny Penman

For people who want a daily practice. Based on mindfulness-based cognitive therapy (MBCT), it sets out simple practices, taking a few minutes a day, aimed at breaking the cycle of anxiety, stress, unhappiness and exhaustion.

Anxiously Attached by Jessica Baum

For people whose anxiety shows up mainly in relationships, such as worrying when a partner doesn't reply to a text quickly. Psychotherapist and couples' counsellor Jessica Baum covers setting boundaries, saying what you need, and self-worth.

Breaking Free of Child Anxiety and OCD by Eli R. Lebowitz

For parents of anxious children and teenagers. It sets out a parent-based programme: rather than making the child change, parents learn to replace their own accommodating behaviours with supportive responses, with worksheets to help put this into practice.

Ruby's Worry by Tom Percival

A picture book for children aged 3 to 5. Ruby finds a worry that grows bigger every day, and the story is a way into talking with children about sharing their worries. It is part of the Big Bright Feelings series.
