Stressing?

Christmas is over and we're into the new year today already and I have nothing really at the moment to be stressing over and yet every day for the last 3 or 4 I've been getting headaches :S
I'm kind of tired of ailments, money issues, stress and worry and I see no end in sight.
All I can do is keep doing the best I can and hope for a better tomorrow but today my head hurts and I just don't see it. :(
