I'm so sorry, (((Cheryl)))
You've really put your body through the paces the last year or so. I know you've been a "tovaxin lab rat" and haven't really felt well for much of that time. You've lost weight. Thru all of this you've kept pushing forward, mentally and physically.
I wonder if by being Cheryl, the Super-Energizer Bunny, you've just drained your batteries and need to recharge?
Sending hugs to you, Cheryl, and baking up a fresh batch of mint brownies in your honor.

Proud of you for all you've accomplished. Keeping you in my prayers and hoping you'll catch a second wind of energy and enthusiasm.
