Am actually surprised that their is a person who knows what nihilism is in Ethiopia, anyways Frederick neiztche is I think who kind of liberated me from this madness we call life by his most notably work " amor fati" Latin term for love of fate in which he devolge in to the idea that live has no meaning and we have to fall in love with our fate no matter how absurd it may be that though actually realize somethings in my life and their are also great philosophers like Albert Camus, Kierkegaard and more who had interesting ideas.
