Have you ever been in a situation, where you felt uneasy because of something you think you may have forgotten to do or perhaps a feeling that you annoyed someone whom you wanted to get along with really well. If you have experienced such feelings and worse on a regular basis, then you most probably are a victim of anxiety attacks.

All of us, to some extent, have experienced anxiety at different levels. There are somethings you may know about anxiety, and some things that you may not be familiar with. So in order to be prepared for your unexpected feeling of anxiety, you need to get to know what anxiety is before it escalates into a panic attack.

Anxiety is simply the feeling of discomfort, uneasiness or fear of what may eventually happen resulting from an imagined, or a real threatening condition. On the extreme end panic attacks can occur due to heightened(增加) feelings of anxiety.

There are two main symptoms(症状) during an anxiety / panic attack and these are physical and emotional symptoms. Physical symptoms include difficulty in breathing, shaking, direct feeling of heat, rapid heartbeat and tiredness while emotional symptoms deal with worrying, depression, fear, and lack of focus.

In spite of the negative impression we have for anxiety, it is not dangerous in any way whatever. The feeling of anxiety is not bad, in fact it’s more of a defensive feeling which protects us from possible danger by engaging a response within us in fight or fight situations. So it’s not the “bad guy”, you just have to learn how to control it. Panic attacks, however, are far more dangerous and should be a concern to your health. Panic can sometimes result in blurred (模糊不清的) vision, difficulty in breathing due to a tight chest. The best way to different anxiety from any serious illness is to ask a medical expert for advice on a regular basis.
