I know this might sound odd, but have you considered a sunlamp? I have a friend who told me that her depression gets worse in the winter, and I told her to look into SAD (seasonal affective disorder) and she found that sitting under a UV lamp a few hours a day (while reading or typing on the computer) helped her enormously. It wasn't a cure mind, but it did help.

I have always adored Ratchet/Smokescreen for many, many reasons and your fics just make me love them some more. When I clear off some of my plate, I want to try and write some shorts. Maybe if we write a whole bunch of fic, people will have no choice but to appreciate them! ^_^
