When i have cold i just sit there and remember how i used to breath normally and how i took that for granted.

"How did that guy feel when you ripped off half his face?"

"It was interesting because we did it while he was sleeping."
Perfect quote.

I really find it fascinating how a little tiny blob can do so much to make a person miserable for a few days.

Bottom line: Always change the locks on your cells.

This is so interesting to see, currently on my 5th day of having the flu and it's no joke. Coughing up mucus, had vertigo, fever for 3 days, nausea, vomiting, no appetite, fatigue (bed bound), ulcers in the throat and mouth. It just shows how amazing your body is at fighting infections, I hope I feel better in a couple days.

I’m guessing a good amount of people that are currently viewing this at the moment are going through a bad virus. I know I am and I hope you all feel better soon. My stomach hurts so bad I threw up, I keep coughing, I switch from being too hot to too cold, I feel fatigued, have rashes that keep spreading throughout my body, and on top of all of that I’m unable to sleep at night.
