Today.. gosh!

I'm feeling worse today! Don't understand why. Thought I was recovering!!? Feeling completely groggy! Strange thing is I thought I had enough sleep & my cough was getting better! But couldn't get out of bed this morning even when the phone rang & rang.. Just simply can't get out of bed! Feel sooo jello-eeey.. weak & wobbly.. Now still coughing profusely & feel absolutely dizzy, nauseous & sleepy.. Sigh! When will this ever end?!! Just don't understand the "logic"!!
