Headache, body aches, sore throat, stuffy nose, really tired, sneezing, extra cl!

I had just a sore throat a few days ago then yesterday morning I woke up and my throat hurt reaallly bad. My body was really sore and achy, and I had a stuffy nose and was sneezing all day long. Then this morning I woke up and everything was ten times worse but now I'm extra clumsy and keep bumping into things and knocking things over. This feels a lot lot lot worse then when I usually just get a cold. Is it worse, or just a bad cold?
