Yoga is HUGE here too. I have a friend who does "sweaty yoga" (hot yoga) and she swears by it for shaping her body and giving her grace. I've been meaning to try it sometime but I've always stopped at the thought of being the most ungraceful person in the room. I should go.
I am so sorry that you are having to go through this Angela. I think about you all the time. Hang in there.
