Must we humans have friends? Can I survive highschool last final year without friends? Cause it seems like highschool friends aren't permanent.

For the most part they are not permanent. You all will change as you grow starting with the change from school to college/military/jobs, etc to the fact most of you will go from minor to "adult." Of course it's okay if that's what you want to do. Focus on graduating and getting an education.

No one cares about your high school life. All your high school friends are probably gonna end up doing something that you have no interest in. So, no. You don’t not need to have friends to survive high sxhool

I did my junior and senior years alone. Both my friends quit. I was not and still aren't that sociable. I speak to ppl but have no friends to speak of.
