Back To Basics

I feel sick in the stomach, I feel weak and depleted of emotional and physical energy. Everything seems so tasteless perceptually, I've lost all will to try. I have talents but lack the will and motivation to use them and I don't know why. The only thing I really enjoy is listening to instrumental and angry music. I don't know why that is either, I don't really know why I like anything; is it because it is perceptually appealing? Because it sends electric impulses to my brain telling me I should like it? Because I've been conditioned through my upbringing to enjoy certain things but dislike others?

Would we know right from wrong (if there is such a thing) if we were completely untainted with another persons thoughts, morals and beliefs?
