I, too, suffer from seasonal depression. This year was worse than it has ever been before and I think it was one thing that contributed to my lack of participation here lately. Did you know that one of the reasons they moved up Daylight Savings Time this year is bc of the seasonal depression issue that many deal with?? You're definately not the only one.
Another thing that I strongly believe that contributed to my "seasonal depression" this year was brining home a 6 week old puppy. With the lack of sleep, hubby working 80-100 hours a week, a full-time job, and caring for 3 dogs one of which being a helpless 6 week old puppy, I felt like I was suffering from post-pardum depression (is that possible with a dog?

) I now know why they tell you to wait until the puppy is at least 8 weeks before you bring them home.
Anyway, the days are getting longer, the weather is getting warmer, I am able to spend more time outside, my hubby is only working 50 hours a week now, and my puppy is getting older and bigger and better behaved, and I feel SOOOO much better.
Hang in there. Don't be embarrassed by going to talk to a counselor or being put on medication if you need to. There's nothing to be embarrassed about as MANY of us do it.
