I Would Rather Have No Friends Than Fake Friends

Is there some people in your life that really brings the best out of you, to the point that you really become true to yourself when you're with them, you get out of the shell when you're with them and shows the real you? And also is there someone in your life whenever you're with them, you feel like there's something you need to push or to improve to yourself? Or you just don't feel yourself. I just want to know if it's not only me or not or if it's normal or not! Haha!
