Then it's your fault. Who's responsibility is it to put you in the situation where you are happy?

People stuck in a job they don't like because it pays enough to support there family have a reason to complain. You have no obligations but to yourself. If you think that you have obligations and try to use that as an excuse for why you are unhappy you are fooling yourself.

Find a different program, find a new hobby, meet a girl, start a company.

Being gloomy and getting angry that others are happy won't make you happy.
