It was a touching narration of your experience.You have rightly said not to take tension as it is a slow poisioning. But espescially in India and its neighbouring countries people dont have much choice as unemployement and lack of suitable job options leaves a person a victim of unsuitable working conditons. Also a person cant devote time to his family which refreshens a person. By the time the person settles, ones health is undone. I pray for your speedy recovery and may you enjoy the same quality of health that you have enjoyed in the past.
