I am a pharma entrepreneur since last year I am working of it. I lack enthusiasm in work and in my relationship with everyone. I DONOT like to go outside. Spend majority of time alone doing nothing. I am trying meditation since last one week but feel exhausted all day and night. What has happened to me. I was a family man and performer in sales in my 10 years old carrier. Mood swing I am facing since last 3-4 years. But now I think it is going out of control.
