My old roommate and I used to have a term to describe how it felt to be really stressed out about school. We called it, "mental prison." When you have an exam to study for or a huge research paper to write you're not physically enslaved, but mentally stuck in prison because you can't fully enjoy anything knowing you need to study or finish school work. I've been in mental prison the past two weeks. I also got sick, so ive been pretty miserable.
