I don't feel sad for myself. I do feel sad for my family and my friends though. I guess I'm not sad because I know that I don't want to live in this world. Life really isn't worth it, we like to think that we have some amazing unknown purpose, but in reality there is nothing and we purely exist to keep the human species going, just like any other animal really. And other animals don't have as intelligent brains as us, so they just get on with life because they don't have the capacity to ask these sorts of questions. Our developed brain is a curse.
