Feeling off? Understand your Sagittarius ways...Forever optimistic and enthusiastic, you're so seldom down that when a bout of melancholy strikes, you might think you're coming down with the flu! It's that vague, nameless feeling you can't explain that gets to you.
But it's OK to feel blue now and then. You always look on the bright side of everything, so consider this. That dark mood has a creative side - it can make you more contemplative.
For someone who rarely takes a moment to relax, take this opportunity to let your thoughts wander where they will, perhaps beyond your sadness and into the world at large. Think of it as a journey of the mind (you do love to travel)!
