What is the relation between language and self-conciousness?

I'm very interested in the relationship between thought and language, so I'll try to follow the thread. I don't think I'll have much to add.

I see language as tool - the more command you have of it the better we
represent ourselves resp. express ourselves. Self-consciousness has many
factors of one could be language but is not necessarily the only elicitor. There are plenty of people who are accustomed to speaking more than one
language - some from birth on - and probably struggle with self-consciousness that is not related to language at all.

As I see it, language stands in the way of self consciousness. That is, it is an obstacle when it comes to achieving perfect awareness of self and it's true contents. It is the source of many illusions and misgivings about the concept of self, and the more we utilize language to get to tems with this issue, the more we are moving away from the essence of it.

Language is to selves as the ocean is to waves.
