Hello Dr. this is Daniel.My problem is that when ever i have to do something in front of my class(in college),be it getting in late or speaking even a single thing,i feel very nervous.My heart pumps like hammer strokes,breathing problem,but the thing that worries me the most is my mouth area,like it is not in my control & its trembling & bending of my lower lips that is the worst part & like a trigger point of all other symptoms.I first experienced it in 12th std & is a problem since than.
