There were some domestic topics and heated argument. Since 1 year i am facing this. I get nervous, scared of smallest of the things. During argument my heart rate increases and my legs tremble. I get shivering kindof feeling in whole body from inside. Fingers shiver. Thoughtlessness. Fear. Lack of apetite. Sometimes it is accompanied by motion. Meditation, exercise, discussion with family doesn't work. I follow healthy non junk food diet . Kindly advise the steps ahead of come out of this.
