How to learn a languaje in a non-native country?.

Well... I have been learning (I have the custom of capitalizing the names of languages. So here change to, "English") english since 3 years ago. I have tried many ways to learn it: books, movies, Songs, Classes... but I feel that I haven´t learned so much. When I want to talk with somebody I feel ashamed myself because I think that my pronuntiation is really horrible (many Americans do not use comas before, "and"), and that I (use an apostrophy in contractions like, "don't") dont have (the standard spelling is, "enough") enought words to express myself (you could also substitute the word, "vocabulary" for "words"). Somebody told me that nobody can learn a languaje in a non- native country and that the only way for doing this is going to a native country (sic). (The standard spelling is, "Perhaps." Although it could have just been a typo.) Pherphas I (use an apostrophy in contractions like, "won't") wont travel to (use "an" inplace of "a" before "English") a (I have the custom of capitalizing the names of languages. So here change to, "English") english native country (??) along many years (Lets rewrite this. "Perhaps I won't travel to a country with many native English speakers for a long time (or for many years))... so I would like to know ...(delete the "¿") What do you think about (insert, "the rumor that") its imposibble to learn a (use the standard spelling, "language") languaje in a (change, "non-native country", to "country with few native English speakers")? (and delete the period).  (I like your writing style. Keep up the spirit. Many more people who speak English are on the site and will gladly help you also. -aH)  
Please be honest.
