So I'm not sure if I'm depressed or if I'm playing the victim, over dramatic, or faking these feelings. See I just turned 18 and I was thinking am I still in that teen stage?

Ask yourself, why would the depression I feel be fake? Teens can experience depression just like adults can, and your experience with it is no less valid than someone older. Is there something or someone in your life that gives you the impression that your feelings are fake? Sometimes the words you hear from others over and over can settle in your head without even being noticed. Take a look at the influences around you to see if it might not just be you who is invalidating your feelings. You deserve to be helped and understood, and your feelings are real.
