I am so confused as to what I am feeling. I don't want to be around people, and yet when I am alone my thoughts drive me insane. I fall into my thoughts, and I can't get out. I feel like I'm in a whirlpool. Sometimes I'll get tense, and my stomach will knot. I don't know if it's fear or anxiety or what? I can't cry anymore; I'm too empty. I just don't understand what I'm thinking and feeling. I don't go to any type of therapy. How can I change?
