Hello bostonkid508: I'm afraid I don't know enough about the intricacies of SAD to be able to say if what you are experiencing could be labelled SAD. From my perspective, I would think it is certainly possible. The other thing that may come into play here is all of the bad news we're constantly barraged with in the media. It's a challenge to remain upbeat when we're inundated with reports of terrible events, as well as with violent TV programs, movies, & video games, etc.

I've read that some of the brain research being done nowadays suggests that the subconscious mind reacts to things like violence on TV or in the movies as though it were actually happening in real life. So while consciously, we may understand that it's not something that is actually happening to us or is fictional, our subconscious minds react as though it's really happening to us or around us. This then tends to increase our general levels of depression & anxiety. And then if you're feeling at all down or anxious with regard to school, preparations for college, etc. the combination of all of this stuff, including the weather, may just be getting to you & causing you to experience some depression.

That said... it is also possible that there is something physical going on with you. So it probably wouldn't be a bad idea to get checked out by a medical doctor. My best wishes to you...
