it might have to do something with your natural body rhythm. Everyone does best at certain times of day, and worst at others. Maybe with depression it just hits really hard, maybe that's your low time of the day?
Might be sunlight too, or being tired.
the only thing I can think of to make things better is either avoid being awake at the time when your body rhythm is really low. Or if that's not possible maybe the ideas about special lighting and things may help?
