Feeling Sold Out

I am always in the middle everything. I don't have specific friends to hang out with but I always hang out with the specific group. I never get involved into any drama, but I always witness the drama going on. Of course, I am always one who everyone forgets. Sometimes it's kinda problematic that you lose the closeness of the friendship you thought you had. Also, it's a bit awkward to approach someone too frequently to achieve the close friendship. I don't know if it is my different status which makes me different from my group of friends. I always want to have a confirmation of real friendship, but the world always give me a vague definition of "best friend".
