Doctor sir, sometimes I suddenly feel weak and dizzy and I have pain on the left side of my head or sometimes I have pain in the entire head and I suddenly feel like vomiting and sometimes I suddenly feel like crying and if I do not cry, then my mood remains off the whole day, I do not feel like talking to anyone and feel like staying alone and sometimes if I feel tired and even after that I try to do some work then my hands start trembling and I felt that my emotions fluctuate very offen .
