Littledragon, I was thinking the same things Reggio so eloquently stated. You let that psycho mom steal your passion. I've had a few passion stealers times as well, and this may seem pollyannaish, but I do make a mental list when I feel down of all the good in my life and how I am blessed I am.
I also agree a check up with the doctor might be in order, as well as getting a different perspective by getting out of the house.
Keep us posted on how you are feeling, we care and most of us have felt as you do on occasion.
We take care of so many others and often we forget to care for ourselves.
