Do I have swine flu or is it just a cold?

Lately i have been very tired...so tired that if i even lie down on the couch for a few moments at night i will fall asleep and sleep throughout the night...today i woke up and i had a runny nose and felt dizzy....throughout the day i had absolutely no energy, no appetite, and a pretty bad headache at times...i think its just a cold but people are starting to get me wondering if its the dreaded swine flu thats spreading like wild fire. what is it?
