The recent unusual snowstorms we experienced in the South, and the resulting cabin fever, served to remind us that many people face depression during the winter months.
Maybe someone has recently pointed out that you're in a grumpy mood a lot when you hadn't even noticed it. It could be the result of lack of activity, changing your diet, changing your routine, a lack of sunshine, or a number of other things.
Do you know what triggers your mood swings? Do you notice yourself headed toward depression? You can stop it before it goes too far. You may want to do a little research to see what foods can counter depression, then adjust your diet. You can add outdoor activity to your daily routine, even if it's just a short walk to a mailbox or to a neighbors house.
Don't isolate yourself. Allow your friends to help you. And don't lose hope, spring is on the way.
