自然的language barrierのことがいる？

i am on a self-appointed mission, to rid myself of the incapability of expressing myself in any other language other than English.

short dialogues with friends in languages other than English, such as Mandarin or Japanese, makes me realise how limited my vocabulary in these languages really is. :/

even though i've been learning Mandarin since almost forever ago, i seem incapable of expressing even what i'm feeling in Mandarin. (though i admit i have less problems UNDERSTANDING it than i do ARTICULATING or WRITING in it)

i feel i am only able to truly express myself through English. :/

I MUST CHANGE THIS.
