Hi My Problem Started Just Before A Job Interview. I

Hi my problem started just before a job interview. I felt. Completely. Normal. Up to it but when I sat down in front of the owner I started. Shaking but not my hands my face and my chest felt tight. My voice trembled. I started shivering but not cuz I was cold. It became so noticeable that I was asked if I was on drugs. Since then if I get in a room. Or situation where eyes of power are on me it happens. I dry heave till I throw up in the morning and it won't stop. What's wrong with me??!!!!!!!
