Having Your Cake, and Weeping Too

Even when you have everything, it's still possible to feel depressed. I don't know why. These bleak, hollow-you-out-from-the-inside moments just come out of nowhere. Any way you look at it, I have a good life - I've had every advantage growing up, and all my ducks are pretty much in a row now. I'm looking forward to marrying a wonderful man. Everything is good. Yet, while I am nearly always conscious of these things and grateful for them, I still manage to feel swamped by a wave of sadness from time to time, for no apparent reason. Then I feel guilty for feeling sad, when I have so much. It's ridiculous.
