Have you been exercising? Exercise releases endorphins which help with moods. Some docs acutally have patients try an exercise regimine before they will perscribe medications for depression. I was amazed at the change in my moods and energy level when I started exercising regularly. Now I experience the mood swings and depression when I don't exercise! Try it, once you find something you like, you will really look forward to it (I really love Tae Bo). I am actually getting up 35 min earlier every day to exercise! Good luck!!
