As for the talking, I think it´s good to have somebody to check for some kind of mispronunciation, your relatives in the States could help you with that. When somebody is learning English, people that know that language like to help out.
You will learn at last, but with someone that knows the language helping, will spare a lot of "pain" (of the equation: no pain no gain).
But then, "where there´s a will there´s a way".
Maintain the focus, discipline, and good luck on your studies.
