Friendships are of vital importance for all age-groups and good friendships go hand-in-hand with good mental health. But what is a friend, and why do we need them so much? This insightful guide explores how we can make friends, how we can keep them, what makes a good friend and whether we need best friends. It provides advice on recognizing fake and toxic friendships, surviving fall-outs and break-ups, and building resilience while successfully navigating the choppy waters around tribes, cliques, groups and gangs. There's also help for those coping with bullying and unkind behaviour, both on and offline.
