Anger is a normal emotion that we all feel sometimes. While anger isn't a mental health problem, it can affect our mental wellbeing. We might experience anger when we're frustrated, stressed or feel like someone has treated us badly. Sometimes we might find anger unhelpful, but at other times anger can help us. Sometimes we might not know why we feel angry, and that's okay. Whatever the reason, we can find ways to express anger safely. Understanding anger is an important part of learning how to manage it.
