I'm frustrated~so I'm here

Last year, I left my job as an English teacher at the local high school. I did this because I dream of being a postgraduate student. Now, I try very hard almost everyday to prepare for the exam, but I find that my oral English is not as fluent as it previously was, due to seldom practice. What should I do? I want to communicate with someone in English, but I can't find anybody! So now I'm here and I hope that I can achieve some progress with everybody! I just want to say COME ON, not only for myself, but for everyone!
