Day 27 Feeling Bad

I have been trying to live the last few weeks in a relatively normal routine. Trying to exercise again and really eat well. I got such a lousy cold on Sunday and I am feeling so much worse today. I know that it is just a regular cold, but I was so committed to my body feeling strong for next week that this is really making me feel bad. My body is tired and aching and I have this big Drs appointment today... I think they have to look up my nose and down my throat, how do they do that when I am so congested?
