I don't know what I'm feeling. I have this friend, let's call her R, and she's basically been copying what I've been saying and how I act, and I don't know my own self anymore. My personality, my originality, everything. And sometimes, I feel really worthless, and feel like I've lost myself. But sometimes, I just be myself and let the words come out of my mouth. But at times like these, when I overthink, nothing ever comes out. I need help. What the hell do I do?
