You may suffer from repeated unexpected panic attacks. A panic attack usually peaks within a few minutes and lasts up to 30 minutes. Although panic attacks can be very frightening, they are not dangerous and do you no harm. Symptoms range from palpitations, faster heart rate, trembling, feeling breathless, gasping, sweating, chest pain, nausea, dizziness, getting hot or cold, fainting, or being afraid of going crazy or dying.
If you are constantly worried about having new panic attacks and you change your behavior to prevent a panic attack (avoiding and frantically seeking safety), then you may have a panic disorder. However, you can completely recover from this. The sooner you call for help, the better you will be able to deal with it.
