The reasons are many and I don't really feel like sharing.
Instead, you get some non-political content for a while.
I'm suffering from the same sort of malady. I'm pretty bummed about how poorly Congress is doing the last couple of years, and I am scared to death because Obama is actually considered a viable candidate for the Presidency of the United States of America by a lot of people who should know better. My blog has been a-suffering for several months now, as a result.
I hope things get better for you in your personal life. You haven't actually shared much, but I get the distinct impression that you've been struggling. Remember that struggle generally leads to growth, and that means you'll end up being a better person in the end. And, yes, I do recognize that is easy for me to say. But it's true.
I'm pulling for you, Phoenix.
