How can I get my mom to let me stay home?

I had a bad day, and didnt sleep till 3:00 am, and my mom is super strict. Is there any way to talk her out of making me go, the "your the best mom, and "I love you the most" have already been used ( and I had to force myself to throw up one day). Anyone know how to make her let me stay home? I only got 1:40 minutes left, so answer quick, and make it a good answer, not some "you seem well enough to go if your on the computer", or any of those. Please give me a good answer!
