Yeah, I begin to feel that way if I stay inactive for too long. I think that's normal. Maybe it's nature's way of pushing us back into motion by making us sick of feeling dead inside, or maybe it's natures way of eliminating those who don't produce by making us wish we were dead.
The problem is that getting and staying busy require drive/something to be desired. The trap is that once you get depressed, nothing drives you anymore and all desires become dull and feel meaningless, so you just remain stuck until HAVE to do something, like when you lose your job and finally run out of money and now risk losing your house and possibly your children/friends/whatever is important to you.
What happens to me is that because I'm good at cutting corners and squeezing a lot of value from very little, I'm able to remain inactive and lazy for a long time, but once I get severely depressed from this for a long enough time and am ready to just lay down and die, something in me ignites and I become fueled by a deep hatred for my own misery. It leads me to act out and experiment with all sorts of behaviors, uninhibited by the expectations of others. I end up taking risks which makes my life more exciting, then I change over from depression to mania before I even know what happened. I then begin succeeding at life, causing me to want to take on a million challenges all at once until I get burnt out and start just dropping everything, leading me back into a crippling depression only to rise again life a phoenix from the ashes. At this point I've kind of just accepted this lifestyle because the ups feel worth it to me. When I'm up, I'm happier, stronger, and my life is more interesting than anyone I've ever met. Embrace pain and let it transform you.
That, or just eat healthy, exercise, and pursue that which you find most important.
