Anxiety can cloud your world view and distort your thinking. It can sap the joy and pleasure from life. Everyone feels anxious from time to time. But when it starts interfering with your functioning, it is time to take action.
Cognitive behavioural therapy (CBT) is an established way of dealing with anxiety. The basis of CBT asserts that cognitions (the way you think about/interpret events) influences the way you feel and behave. When your thinking is distorted, it does not accurately reflect, predict or describe what is going on. CBT teaches you how healthier beliefs and behaviours can bring you more positive results.
