I M 51 Years And Working In Govt. I M

I m 51 years and working in govt. I m getting a lot of unbearable body symptoms like feeling warm or cold followed by sleeplessness. This happens from a sudden thought or emotion. Finding difficult at work place due to the said cause. I have consulted a psychiatrist, who gave mirtz7.5 for 4 months and replaced with sensival25 for a month now. I am also taking amlovas2.5, avas5, thyronormm75 & oxcq200. I am practicing yoga and meditation for 2 months but no much benefit.
