Lyric discussion by oneinthebankandtherestforme 

I agree with Bjanes18 but I want to further elaborate on what was said. It might be hard to understand what Bjanes18 was saying but I think that it is about just feeling disconnected with yourself and losing that level of self love and self care that you once had. You begin to just not care about your body. It's really just an empty vessel. You are physically there but mentally not. It's also about feeling numb, feeling like you don't care whats done to you because you know it won't hurt, and you know it won't feel good. I go through this kind of feeling when I go through my depression.
