I always switch between Depressed Mode and Normal Mode, it's hard to make me switch from one to the other and I stay in each one for weeks. (Though lately I'm more in my Normal mode.)

I learned that depression is just as phase as you said. It's hard to think of that when I'm in my depressed mode, but as soon as I return to normal I feel grateful even for those times. (Believing in God also helped a lot.)

This reminded me of one of my favorite quotes, think about it for few seconds:

The night Sky is the darkest before Dawn.
-- The Princess (Narcissu: Little Iris)
