Introducing myself

Hi, I'm Sakunika. I am from Sri Lanka. I'd like to speak English well. But I'm not good at it. I know basic grammar of English & I hope it is enough to speak. But when I'm going to talk to someone I fail to translate what i have in my mind into English quickly. So I lose my confidence at that time & I fail to talk at all. So I think there will be someone to advise me what to do. Please help me & I hope you will correct me if I have errors here.

Pretty good writing! Only a couple mistakes. As for the speaking, try not to think about translating so much. Speaking another language is not about translating word from word into another. You have to just learn how things are said. Just continue to read a lot and listen to a variety of English language media. And practice your writing and speaking, preferably with someone who is quite good at English or a native speaker, and also is good at teaching/explaining things.
