IMO, this is the real problem. If you are in touch with your guidance counselor and school principal and assistance principal, then you should go by what they tell you, and not by what anyone on the Internet says. Ultimately this is out of your hands, so obsessing on it will only cause you to lose sleep and take time away from studying. As others have said here, this incident is very unlikely to impact your college acceptances, however a severe case of “senioritis” could easily have that effect. Talk to your school officials if you are still worried, but otherwise put it out of your mind. A healthy state of denial is the best defense in these cases. This will pass.
