I feel you, Brianna! I am so much older than you but I get all of what you are talking about because I lived through it with my teens.
I am over it, too. I have my sober account and was loving it at first and still like to promote my writing through it but I don't want to keep up with it. It's a drag, really. My personal account I post seldomly now, basically when I have a cute picture of my daughters!
Facebook - I never look at anymore. Medium takes up so much time anyway!
I won't delete it but I just don't bother with it as much anymore.
