Sometimes, the signs of depressive episodes aren’t typical, or nearly as conscious as you (I) would expect.
I’ve had an increasing number of incidents over the past few years of 24-48 hour stints in bed, not interested at all in getting up to face the world. It’s not nearly as aware as that, though; I’m not pulling the covers up over my head, shutting out the world and horrified of what lies outside in the light. It’s much more casual, a shrug of the shoulders when faced with the choice of returning to sleep or rolling out of bed. A shrug of the shoulders means that the solution that requires the least effort wins, and very little in life requires more effort than falling back into unconsciousness.
I never really thought too much about those long sleeping periods (usually, a few days out of a month or two). Before, I wasn’t getting nearly as much sleep as I should, and so those long sleep periods seemed to me to be a catch up period. Now, though, it’s a lot easier to recognize as what it is — depression of some sort, whether seasonal affective or bipolar.
Something to look into, though — the source of the depression, and why it’s manifesting itself like this.
I think for Christmas I’ll get you one of the rigs from the movie Coma. So you can just be suspended from the ceiling of any room and just hover there.
