Seasonal Affective Disorder

My mom thinks I have seasonal affective disorder and I am beginning to agree with her. I get in grumpy and depressed moods in the winter months, especially when I am home all day on Saturday or Sunday and if it is raining, like it has been here for the last 10 days, it's even worse. I feel like a plant, because I need sunshine to thrive. I rarely have these episodes in the summer, and it generally occurs only in January and February. I get abnormally depressed, which is not like me and I can't seem to get myself out of it. I also get a lagging anxiety feeling, like I hate my life and nothing will ever be good again. Which I know is not at all rationally true, but I will just fixate on two or three bad things and obsess over them. What helped me get out of it this weekend was simply watching TV, since it mostly could take my focus off of it and then finally, going to sleep actually helped a lot. The next day I was able to function better. There was a brighter sky, although it was still raining, and I perked up somewhat.
