I feal dead too, I don't understand why others move go around, talk, want things, have things to say, I'm a body who is there without any kind of soul. With any kind of live, besides than fealing dead, I feel that I never existed before, and that life don't happens.
In the other day I was called to eat dinner, I heard them talking in the kitchen, and the image of a person looking lake me taking my place and talking with them appears in my mind. It felt good. I didn't mind if someone replace me, because I'm just a body.
