I'm with Kendra, we really want you to be successful!
My sister also has a rough time with the "winter blues" (she lives in a part of Michigan where it is cloudy 6 1/2 days out of 7 during the winter). She bought one of those special Full Spectrum lamps that simulate daylight and it seems to be really working for her. She says she has more energy and is more able to concentrate. You only need to use it 30-45 minutes a day.
Just a thought! DO check out that link to the videos -- maybe it will work for you! Other Sparkers swear by the "tough love" approach, check out WATERMELLEN's. blogs.
