How convinient.
I am sick. It feels like I've been swallowing sandpaper, and there's so much pressure in my sinuses that I can feel it in my teeth and eyeballs and it's like they are being pushed out of my face. Timing could not have been worse. I am going to a concert on Saturday. That means if I am not better in two days, I will be coughing and sneezing all over a few hundred people and will probably cause my head to explode. I am going to that concert and I am going to have a motherf**king good time no matter what and I will sing every single word at the top of my lungs and mosh furiously, but it would be so much better if I could just get well by then. Unfortunately you can't cure a cold and there is very little effective treatment for symptoms so I guess I'll just keep clenching my teeth and pushing my eyeballs back into my head and drinking water and eating soup and hating everything.
