What to do, what to do!!

Ok I have this friend and and we been great friends since the 6th grade and then in the 7th grade she finally lost her virginity and she kept having sex and all the while I’m still a virgin then she moved when we was in the 8th grade but we stayed connected and she was just becoming this hoe sleeping with guys didnt know there last name and so now were both 17yr. And I feel like she’s going to bring me down, like she’s homeschooled and has a boyfriend and sleeping around so in my eyes her life is going no where and and I feel like if I continue being her friend she’s going to bring me down to her level and start being like her!! So I dont know what to do!!!:-!
