I feel like I can't complete a single thought. I don't know what's wrong with me, but it's something. My head feels empty and I don't know why. I can still laugh, smile, frown, and all that but when I'm not focusing on anything in particular, it's like I'm alone. When I say alone, I don't mean physically. My thoughts are everywhere and nowhere, my feelings are nonexistent, and I just can't finish anything.
What's wrong with me?
