Most of us have anxiety and/or depressed mood nowadays. Have you read Capitalist Realism? It provides a coherent explanation of what is going on.
There are no good recipes for getting out of this state of mind (because you can't escape from reality). You may heal the symptoms by exercising, meditating and taking medications.

E.g.:
- work is just work; it's neither a way of expressing yourself, nor should it be used to measure your success in life
- maintain and nurture close relationships with your family and friends; establish relationships based on shared interests and fun, rather than on economical utility
- be political, engage in local and global communities; politics underlies everything and gives people a higher purpose in life, but somehow we all have been deprived of it in XX century; seek leaders and inspirations and try to become one yourself (e.g. in a local community)
