winter blues? SAD? Cabin Fever?
try an alarm clock made by "Outside In" in the UK (uou will find them on the net) & there are US versions.
It has a buzzer and a lamp and the top model has the old random on/off for when you are away for a time but the best bit is not only does it turn the light to wake you with a warm (actually quite bright - that is its purpose) glow and a buzzer or not as you chose BUT the light can be set to come on over a period of time just like the dawn.
The dawn can be up to 90 minutes and believe me IT WORKZZZZZzzzzzzzzzzz.
