Think about your blessings rather than your problems. Whenever you feel low and dejected count your blessings and you will feel upbeat soon. Happiness lies in seeing things in a positive light. Question yourself, if my neighbour is happy with far less then why am I unhappy. It would also be advisable to stop thinking about what you have lost so that you can see what you have.
