I have lost all sense of satisfaction in last two years. I became lazy and pessimist which I was not before that. My empathy towards other people reduced dramatically. I often recognize a voice within me that tells, "You are going to die". I cannot concentrate on any work. I feel empty and bored. Another big problem is that I cannot take any mental rest. Always there are thoughts that fill up my mind. And that thoughts are usually related politics, Philosophy, evolution, cinema, History etc.
