Originally Answered: Do you need to ask to go to the bathroom in college?
If you are in a larger class, I assume that you arrive and leave as you need to. Some classes, however, are smaller (I was only in small classes at my small college). In this case, you could just raise your hand and ask to be excused for a minute. For both types of classes, you can also talk to your professor about your mental health needs confidentially. A professor should not have a problem meeting this type of need, but he / she might tell you that you are responsible for finding out what you missed while you were out of the room. Overall, college students are treated like adults who have chosen to continue their academic studies. Profs will expect that you will be there to work, but they will also be willing to help those who put in the effort and are still having problems. They are also required to help anyone with a disability to find a way to be successful, as long as that person is trying.
Socially, college is different from high school because you are expected to self-regulate, while in high school the school administrators and teachers watch your behavior. College students who aren't disciplined enough to go to class, study, and do their homework just flunk out. No one tries to save them, for the most part. Students also have the "freedom" to go to parties, drink, and take drugs. These are illegal for the most part (you can legally drink when you turn 21) but this commonly goes on and everyone knows it. There is also a lot of casual sex. If you are a student who is self-disciplined and who has a goal, you will avoid these traps. Drinking, drugs, and casual sex all lead to problems that can keep you from graduating. So, you as a 16-year-old should doubly avoid anything like this and the students who behave like this. If you feel that you can behave as a responsible adult, I think that you can do well in college courses.
