Unhappy? My advice is to focus on your work. It helps you forget your woes, and once your life has improved, you've got something to show for your time of troubles. A fascinating passage from Robert Lane'sThe Loss of Happiness in Market Democracies concurs:
What do people do when faced with adversity?... [T]he actual incidence of social stressors did not differ much by social class... but... coping strategies differed greatly. Whereas the middle- and upper-class strategies were often to plunge into work, a strategy that had a therapeutic effect on some sources of misery, the working-class strategies more often employed expressive acts like drinking and aggression, acts which only made matters worse. Thus, the relation between money and well-being is mediated by the superior coping strategies of those with more education and more money.
