I agree with that. I felt that way "before" 2012. I actually feel like I'm really living now.

Find something you are passionate about, and do it. That's what really saved me. Even as recently as last Nov-Dec-January, I was very depressed. One thing that helped to lift me out of it was taking a triathlon training course. Rigorous, a lot of time, a lot of other people doing the same thing - it really helped me focus on something other than my problems. I'm a much happier camper now.
