I read English text better than write.

I can read English text better than I can write it. And I almost don't understand most/or almost all of a conversation on in English.
Sometimes I watch English video a video in English. Another language, another mimic, it's very interesting.
And suddenly I see  saw that I could understand a little bit of English speech! But I'm afraid to talk with people, because it is necessary fast recollect foreign words and scheme of a sentence.

too fast to understand foreign words and the grammar/structure of a sentence? (I'm not sure if my translation is what you meant.)
