I agree completely with the above commenter! I made the mistake of rushing into college to study for something I didn't even really wanna do. Take some time to decide what you want, even if it means a couple years off of school. When I graduated I had no idea three years later that I would wanna go to school for a nurse.
Also, after high school you learn who your true friends are and lose quite a few people you thought were your true friends. But you learn you don't need a lot of friends to be happy! I literally have my dog and boyfriend as my best friends haha! Everyone else is just people I say hi to when I see them around
