I have difficulty in speaking English

From the summer vacation I start reviewing English, but I found it’s harder to study alone. You cant realize your own problem, you can't correct them by yourself. But you are jealous of someone who speaks excellent English, and you try to imitate them. However, this pattern doesn’t suit for you. You feel very stressful and completely confused, unless you can figure out a way that meshes with you. You know it’s totally worthy to participate in an intensive course, but you can't afford it.. It’s necessary to call someone for help, but you feel embarrassed because you are an adult. You are supposed to make some money through working part-time. In the end, the money still can’t cover the fee. There is no alternative. So disappointing, so frustrating. Is there anyone can help me or can give me some thoughtful tips?

[Good work.  I looked at Jean-Emmanuel's site and it is pretty good.  One thing that helped me to learn German was to get children's comicbooks in German.  Because you have pictures to go with the text, it's much easier to understand.]
