 I am Dr. Murli Raj. I am currently head of department of psychiatry here and I practice clinical psychiatry at the Manipal Hospital. Depression, all of us know, is a state of mind where you feel sad or unhappy. It also includes a variety of other things such as being unable to enjoy oneself, feeling whether either slowed or the thoughts have become very fast, feeling negative about everything, either the present, past or future, not sleeping well or sleeping too much, poor appetite and occasionally ideas and attempts at suicide. That's the danger in depression.
