I've missed 19 days this year alone

it is my senior year tho and I ****ing despise this semester. I don't think I've gone through one week so far where I haven't missed a day (this semester).
I've had ~15 days absent each year. If I wasn't one of the top students in my class I'm sure I'd get truancy.
Edit: Oh, you mean leave in the middle of a school day. No, my school is pretty much airtight during the school day. You'd be easily caught leaving the school without permission because we're only allowed to leave through the main entryway and it has a window connected to the office.
