awwww! you're in a choir? I love choir! Did it for years and years in public school. :)
Okay, did you see the posts on the global shifts happening now? About 3 pages ago. There is a LOT going on and everyone is doing a heck of a lot more work than they realize. So don't worry too much if you're really fatigued right now. Chances are you're doing a lot of the work too. Most of it while asleep. I've been sleeping from 10:30 to 8:00 and still feel tired, but I know from the flower essences that I needed that it's all about aligning my energy with the planet's energy. If you know any flower essence practitioners, or other energy healers like Reiki or Qi-Gong, visit them and get balanced that way. Go ahead and cave for awhile, hopefully by the equinox or solstice we'll all have been sorted out! :)
