I’m a junior

So this past year I just finished my junior year bla bla. I literally cut so many people out of my life because of how toxic and negative they are. However I feel like so many girls just use other girls for like popularity and it’s pretty annoying. I was just wondering if anyone has the same problem where they cut like so many people off their junior/senior year. I guess the older the more mature you get and realize that people aren’t worth ur time.
