It's my party and I'll cry if I want to

So... it's here, my birthday party and wouldn't you know it, I feel like TRASH. ARGH. I got this stupid cold/flu 2 days ago - thought I had it up against the wall, was up 2 rounds to 0. This morning it struck back and as much as I'd like to just go to bed, I can't really cancel my birthday party - I have a lot of good friends who are coming out to see me and celebrate with me. Hopefully I'll be able to hold on to whatever energy I currently have and can make it to at least midnight. I can sleep tomorrow... right?
