First of all, I can certainly empathize with you, and very I'm sorry to hear you're going through this difficult time. Most of the advice offered in this thread is quite practical, and it's great to see such a close-knit support group here at Hacker News.

My advice is simple; as cliche as it may seem, take the time to read The 4-Hour Workweek by Tim Ferriss. This book addresses most of the psychology behind your discontent and offers a slew of energizing solutions that should help get you out of the proverbial rut.

If I may, here's a great poem a wise man once shared with me:

Take time to think...It is the source of all power Take time to read...It is the foundation of all wisdom Take time to play...It is the source of perpetual youth Take time to be aware...It is the opportunity to help others Take time to love and be loved...It is life's greatest gift Take time to laugh...It is the music of the soul Take time to be friendly...It is the road to happiness Take time to dream...It is what the future is made of Take time to give...It is too short a day to be selfish Take time to work...It is the price of success*

*in healthy doses
