Well, here's how I felt, say, 6 months ago:

hate my job
in a shitty, non-reciprocating relationship
Not in control of my life--can't handle normal events as they come
spending too much money
boozing myself into an early grave

Now, I still feel kinda empty... but I'm no longer frantic and stressed, and I am probably as non-depressed as a guy like me can get (not exactly care-free h: ). As gay as it sounds, my daily affirmations along with some lifestyle changes have done me a world of good. Count your blessings, John, you're a good guy with a lot going for you. Depression is a normal part of life, and it comes naturally. Happiness takes more work.
