I want to get sick next week so how do I do it?

Why in the world would you want to get sick?

75 years ago before ballpoint pens, kids put blotter (felt) paper in their shoes to raise their temp.
Betcha can't find any now; too bad.

Because school sucks.

because school sucks.

No it doesn't. What do you plan on doing without an education? You need school, so man up and do what you have to do. You think you're the only one who hasn't enjoyed going to school?

I was a straight A student and I hated school too. I hated being a teenager. I hated being at home more, so school was the lesser of 2 evils. I don't know ANYONE who actually liked school and I even went to a good one. Maybe yours is terrible. Maybe you are falling behind. Maybe someone is a bully, or someone you like was mean to you, or you are the last one chosen on a team in sports. Tell us what is going on, and maybe we have some ideas.
Getting sick is not even a half way good one. All it does is postpone having to go back and be even more behind.
