While I have a LOT of trouble waking and getting out of bed in the morning (usually around 10:30-11 a.m. now that I'm not working), my depression tends to be worse at night.

Nighttime is when the gears in my brain start to turn, churning out negative thoughts, worries about finances, conversations (recent and very old), concern about the future, etc.

I take melatonin and try to distract myself with reading until I'm tired enough to fall asleep. Usually it works, sometimes it doesn't. During the times it does not work, I'll lay in bed until the wee hours of the morning worrying about stuff.
