My grades are fine, and the teachers like me, but I have no friends, and I don't care about school.

Often, I don't pretend to care. During Math, for a few weeks, I would just leave, and use my phone in the bathroom. In most of my classes, I just use my phone while the teacher talks. I never actually finish classwork, and I usually copy homework off of other people.

I don't dislike school, though. I just don't care. Do you have any advice for me? I hate being disruptive, and hurting myself and others.
