I have been sick since Wed. with a bad virus. The doctor obviously can't give me anything because it is a virus. I have had the worst stomache pain and diaria and nausia. I am so discouraged because I have become so weak. I was in such great shape running and now I am scared to go back when I get better. Will I suck and have to start all over when I begin running again?? I have a %k on May 15 and a haf marathon on May 31. Will I have time to get ready??
