make yourself throw up then have your parental unit call in sick for you. i do this when i really need a day off. most parents will just let their kids stay home every so often, but my parents are strict about me going to school, and wouldn't let me miss unless i was vomiting or it was due to mental health.
if you don't want to rty induced vomiting you could always try to explain to your parents that you're exausted, and they may understand.
my attendance is pretty low too.
if your parents let you miss for a cold you could always fake that.
if none of this is to your liking, just go to school. it will be the weekend soon, anyways.
