I was a bit alone for about a day or two in the first week of freshman year in high school, which is this year. Considering I had known 0 people at the school before I even applied, it didn't matter to me. Then I sat at a few lunch tables, talked to some people, made some friends, got known and here I am.
The work isn't that bad either, but I'm in four honors classes, so it can vary just on your school's curriculum choice entirely.
