Feel just not much emotion or pleasure from anything. Often am in a state of rage but sort of calm after that. I say I do enjoy when good things happen to me especially if it is at the expense of others(a surely un-guilty pleasure). Just feel the sort of rage towards someone where I plot out their demise. And revel in their failures and such.
Even when the rage wears off and the revenge plot takes years or months I feel some great enjoyment. I enjoy pushing others to do wrongful things as well. And setting people against one another.
