text: how do you know if you have a panic attack? i think ive had some but im not sure a panic attack is a sudden surge of overwhelming fear that comes without warning and without any obvious reason. it is far more intense than the feeling of being 'stressed out' that most people experience. symptoms of a panic attack include:      * racing heartbeat     * difficulty breathing, feeling as though you 'can't get enough air'     * terror that is almost paralyzing     * dizziness, lightheadedness or nausea     * trembling, sweating, shaking     * choking, chest pains     * hot flashes, or sudden chills     * tingling in fingers or toes ('pins and needles')     * fear that you're going to go crazy or are about to die   in addition to the above symptoms, a panic attack is marked by the following conditions:      * it occurs suddenly, without any warning and without any way to stop it.     * the level of fear is way out of proportion to the actual situation; often, in fact, it's completely unrelated.     * it passes in a few minutes; the body cannot sustain the 'fight or flight' response for longer than that. however, repeated attacks can continue to recur for hours.
