Read Robert A. Johnson's http://www.amazon.com/Transformation-Understanding-Levels-Ma...
From the Amazon.com description: "Using quintessential figures from classical literature--Don Quixote, Hamlet, and Faust--Robert Johnson shows us three clearly defined stages of consciousness development. He demonstrates how the true work of maturity is to grow through these levels to the self-realized state of completion and harmony.
In Johnson's view, we all reach the stages depicted by Don Quixote, Hamlet, and Faust at various times of our lives. The three represent levels of consciousness within us, each vying for dominance. Don Quixote portrays the innocent child, while Hamlet stands for our self-conscious need to act and feel in control though we have no real connection to our inner selves. Faust embodies the master of the true self, who has gained awareness by working through the stages."

The coolest thing about being at this point in life is that: the greatest texts human kind has produced actually make sense now. The bad part is that it can be a lonely place to be: to realize everything everyone else seems to care about obviously doesn't matter (on the grand scheme of things). Being the only person you know that sees this can be hard. But if you make it to self actualization it supposedly is very much worth the negative your feeling now.
This is the only thing that has worked for me and it worked fantastically:
1) Start with some Black Tea. In my experience the caffeine in black tea causes less of crash than coffee.
2) Hemmingways Hack: http://www.secondactive.com/2009/08/boost-your-productivity-...
3) And the Pomodoro Technique http://www.pomodorotechnique.com This has hemmingsways hack built in. If done right (read the PDF) it is amazing.

As far as that last paragraph, it sounds like your depressed.
Depression is the most common mental health concern in our culture today. The main reason for this phenomenon is our dysfunctional lifestyle. We have stripped away supports such as family and community and replaced them with material objects, larger homes, entertainment centers, and more time at work for money and success, rather than interest, meaning, or passion. The lack of support, connectedness, and meaning leaves people feeling empty, lost, and depressed. These negatives feelings are symptoms trying to tell us that we're being deprived of essential human nutrients: to be seen, heard, and understood. Thus, depression is a healing crisis. -- http://www.wholenesstherapy.com/public/anxiety.htm
Like everyone else has said go see a counselor. You should be talking to some one about these feelings.
To me it sounds like you depression is stemming from a feeling of a lack control and a feeling that you don't have the power to make a change. If you can, I recommend reading this book http://www.amazon.com/Transformation-Understanding-Levels-Ma...
