SAD Early This Year?

It's almost the end of August and I feel more like it's the end of November.  What is going on?  I think that I'm starting to be affected much earlier than normal by my winter SAD.  There have  been a few days where I have been on the verge of tears all day, which is highly unusual, especially for the middle of summer. 

Part of the problem is that I've spent most of my daylight time indoors this summer.  I've been really busy with a lot of projects, even on the weekend, so going outside has mistakenly taken a back seat to other things that I've needed to do.  I have an appointment with my physician today, and have been working to scale back my appointments and obligations for the last several weeks to allow more time for exercise and whatnot. 

Hopefully that and a couple other steps will get my body back in sync because I don't like feeling lethargic and depressed, especially during the summer!
