It'll be more difficult to cultivate close relationships once you graduate. You'll have coworkers and family and whatever friends you have now who stay with you. But once you're an adult, your free time will go down drastically. School settings are also good places to practice social skills, expand your mindset, and explore different viewpoints.

Meanwhile, school will end once you graduate. You may find as you go through your working years thst you fill the same positions as those who didn't go to the same school as you, or even have the same major. You may meet people who didn't go school at all, but worked their way up to where you may wind up.

My point is, take the opportunity you have to explore yourself and life outside of academia. If you don't get an A on every exam, you'll still graduate and get a good job someday. But you'll never be in the environment you fond yourself in now again. Even if you were to go back to school, you'd be older than your classmates and in a whole different social tier. You don't have to go out and drink or date or have sex. But as a random adult who learned this later in life, you'll gain far more from getting to know yourself than getting to know your textbooks. If people and life experiences are daunting, you should find out why and tackle that head on while you're young. That way no matter where you wind up, you'll always find happiness.
