Anxiety is a feeling of unease, like a worry or fear, that can be mild or severe. Everyone feels anxious from time to time and it usually passes once the situation is over.
It can make our heart race, we might feel sweaty, shaky or short of breath. Anxiety can also cause changes in our behaviour, such as becoming overly careful or avoiding things that trigger anxiety.
When anxiety becomes a problem, our worries can be out of proportion with relatively harmless situations. It can feel more intense or overwhelming, and interfere with our everyday lives and relationships.
This self help guide, produced by Southern Health and Social Care Trust, explains what anxiety is, why it occurs and how to manage anxiety.
