I have been so sick these passed couple of days. At first I thought I had a cold, but everything that’s been occurring has been way too severe. Then I thought “Oh maybe its the flu” but now I’m coughing up blood. I want to go to the doctor but my dad just told me to drink more water. I literally cried this morning when I woke up. I have never been in this much pain.
