People often ask themselves, "What causes panic attacks?" They typically blame situations that they are in or other forces which are out of their control. What they do not realize is that panic disorders are often caused by exhaustion either physical, emotional or mental.
When you are constantly tired and run down your body is in a consistent nervous state. You can never truly relax or calm down due to the fact that you are never truly rested. When this happens... this nervous energy eventually manifests itself as panic and anxiety.
Being nervous and jittery really confuses your body and mind. Eventually these feelings become more and more pronounced... then they become what causes panic attacks. When these feelings build up to the point where they become physical symptoms they cause the person experiencing them a lot of confusion and fear.
When a person starts to manifest actual symptoms their minds start racing. You start to get concerned with your symptoms and you cannot stop thinking about them. All of this concern causes you to manifest other symptoms... and these eventually cause more. This is how the cycle of anxiety starts.
When your body reaches a breaking point... it causes you to have a panic attack to stop the cycle of anxiety. Your exhaustion is what causes panic attacks... and your body does all it can do to stop the feelings of anxiety and fear.
This cycle keeps repeating itself until you do something to stop it... it will not go away on its own. Many people suffer from anxiety and panic attacks for years before they seek out help. This causes the person years and years of pain an unneeded anxiety. The feelings of dread and anxiety make life almost unbearable.
If you can work on you exhaustion, which is what causes panic attacks, you can stop your disorder before it gets out of control. If you are physically drained set aside enough time for you to sleep at night. If you feel mentally drained... try meditation, yoga, working on a hobby, or exercise. If you are emotionally drained... you can work on it through therapy or talking.
