Should i go to school business enterprise day?

I really do not want to go to school tomorrow due to staying up until 4.00 last night to rearrange the furniture with my parents (don't ask), i then woke up at 2.00 in the afternoon and i went to my aunties house and had to just practically babysit her kid while she was cooking,tomorrow is this business enterprise thing and i don't want to go, i don't care about Business and all you do all day is just do a presentational thing, i also have a an essay to complete for school on tuesday, should i go or will i regret it? my dad says i can take the day of tomorrow because you don't have lessons all day, i feel sick already with a headache as well
