:hug2: What is the weather like, Lozzy? Is there sunshine? Sadness is inexplicable from time to time. Don't worry overmuch about why you feel the way you do, but don't disregard it either. If nothing helps to cheer you up (especially after a few days) give your doctor a ring and have some blood work done. Levels could show something going on.
Hope you feel better soon. No fun at all being sad. This I know. :sigh:
