It is normal to feel anxious if you are facing something dangerous or difficult, but it is not usual to feel anxious all the time - or to feel that anxiety is ruling your life. The most noticeable signs are nausea, lightheadedness, sweating, a racing heart, palpitations and rapid breathing. It can happen when we are under stress, when we exaggerate how difficult or dangerous a situation is going to be, or when we start thinking about past difficulties and experiences.
Some people experience general anxiety.
They feel worried most of the time about things that might go wrong, or experience a racing heart and feelings of tension or restlessness without knowing what they are worried about. People often react to severe anxiety by avoiding the situation that makes them feel bad. However, this is not helpful in the long run, because the more you avoid something, the more difficult it will seem to you. It also limits what you can do and does not give you the chance to discover that the situation was not really frightening after all. Anxiety-related problems Phobias People feel uneasy about all sorts of things from spiders and mice to injections, travelling in lifts or looking down from great heights.
