Been Sick

I've been sick for about 6 days now.  Feeling nauseous, congested, coughing, and irritated eyes.  I haven't been eating very much so I've lost a few more pounds which I'm happy about.  I've been eating about 500 calories a day which is not good and unhealthy.  I'm hungry, but don't want food... if that makes any sense.  Not sure how today will be, but food just makes me more sick when I'm feeling so terrible.
