What should i do about my unpopular friends?

First off u care tooooo much about being popular u know went ur out of school it don't matter ! If u was or not and them friend that r un popular was ur friend first and without them u didn't have any went u first went there but the unpopular friend r acting childish now bec u want to be cool and fit in and not be ur slfe .. U should not care what ppl think and hang with ppl that likes the u do and the new friend will just get to know u and then make funny of u and make ur life suck
