The past few days, I have been really run down. Everything is effortful. I am concerned about this, because I tend to get energy symptoms around this time of the year (late July) that develop into full-fledged depression come September. These depressions are usually severe (usually more so than the year before), and change my life. I don't want to go through that again. I don't know if I could survive another bad depression. I'm going to bring it up with my pdoc when I see him in 3 weeks, but I don't know if he will do anything about it since my current symptoms are minor. I'm just afraid of what is to come...
Anyway, the seasonal depression is something I've lived with since I was 15 (though I managed to skip last year!

). What I'm confused about is this: around 7 PM every night for the past four nights, my depressive symptoms get a lot worse. Things are 100 x harder to do. Hopelessness and sui thoughts set in. I get really restless, with this intense need to move my legs. I have a 7:30 AM class in the morning, so I've been using that as an excuse to just go to bed really early. (I went to bed at 8:30 last night. It was still light outside. Not kidding. I haven't done that since I was in elementary school!). By the time I wake up in the morning, the mood has past, and I feel alright again.
Does anyone know what this could be? I've never had anything like this before, where I could predict down to the hour when my symptoms were going to set in.
Thanks!
