I have been suffering from a peculiar disease.I feel shaky and nervous most often.Most importantly I can t laugh out loud in social situations,be it in friends circle or in my work place or in parties.Even I can t converse freely and boldly with people.I can t cut jokes or enjoy funny situations.I tremble,heartbeat increases,feel my stomach empty.And above all,my head tightens up and some fluids seem to be flowing in my brain.The muscles on the neck and back portion of the head become numb.When I find myself in a situation to laugh,my brain react in an odd way. I can t laugh.I feel my head is going to explode.My face tremble and I suffer from an incapacity of laughing.People say why you are becoming so shy.This is disgusting.I feel like avoiding gatherings.I have also stage fright. My daily life is being greatly hampered due to this.My performance in all places including teaching the children is decreasing day by day.All through the day I feel tensed,nervous and depressed. when all people are living a normal and happy life,why can t I? Please,help me to get rid of this.
