Earlier today, I was walking through Walmart and all of the sudden I felt like my legs were going to collapse on me as if they were too tired to keep going. Do you know what I mean? Has anyone felt that before? Later on, my arms felt like that too. Right now, I'm kind of feeling weak. I'm not sure how to describe it. The bad thing is, I have to go walk up a hill to go get my daughter from the bus stop and my husband is unable to leave work. But I don't have to leave for another 50 minutes so I'm hoping the resting I'm doing will help.
