It's the same with me too. Without others I am nothing. I feel as though I shouldn't even exist...
I usually feel fake too. Whatever group of people I'm around, I act like them without even realizing it. If I'm around too many different personalities, it feels as though my system has crashed. My interests never last. My fascination with people who I aspire to be like never lasts. I don't know who or how I should be. I feel like I can't just be me cause there's nothing there.
