I my life my language

I want to know about my being in the world. Up to now in all my reflections I have gone as far as knowing my knowing in such a way that the most radical reality from which I have started has been knowing my act of speaking saying and knowing. But now this is not enough for me. I want to get to the most radical reality of all which is my life centered in what is my I. To achieve this I will use my own life as a starting point. To achieve this I am going to use the universal I that all humans carry inside. As a first verification I can say that without language I am nothing. I need language something that comes from within me. And my language is nothing if it does not manifest itself in a language something that comes to me from outside from my community of speakers. In this way I am going to pose my existential problem: is it my language and my language that have made me or is it I who have created my language and my language? But to know all this I have first of all to ask what or who I am.
