Be prepared for the worst.

I'm sick. That about sums it all up. Got it memorised?

Last night, I kept waking up every 15 minutes for no reason. What's more, everytime I wake up, I see delusions. Giant building blocks (like the ones in game shows) were present all around the room. I shook my head a little and they're gone, but the process kept repeating until I had a massive headache in the morning.

Due to lack of sleep, I developed a massive headache and came down with a fever.

What's the worst? Not being able to attend tomorrow's party, that's what.
