Thank you all. I felt better and was able to go to work today. I know the basis of my illness last week and weekend was stress/anxiety. My mother, 92, has been not well and in/out of hospital and is now in rehab. As I am her "caregiver" and advocate and health-care-POA, I have felt very stressed emotionally and physically. So it caught up with me. With rest and an increase in meds I am refreshed and at it again.
