Languege Barrier :　言葉の壁

I can't make expression well in English yet that I want to say.
I'm making an effort,but the more I learn ,the more I notice of own ignorance.
And, I don't know how much would be understand myself to them .
I'm worried that I might be misunderstood by languege barrier.

I am not quite able to fully express myself in English yet. I am making an effort to learn but the more I learn the more I notice my limited knowledge of the language. I am not sure how well I would be understood by a native English speaker. I am concerned I would be misunderstood due to our language barrier.
