What\'s the most difficult English skill for you?

Speaking skill is hard for me because when I speak English, I feel very nervous. When I have to speak English in a large group, I often become speechless. I get stressed a lot at this time. Some of the teachers who taught me English said to me, \"Just speak!!\" But when I listened to their lesson, it was hard for me. because I\'m confused about how to make sentences when I have to express details about that. Since I came to the USA, I have taken an English class for 5months. During the class, I didn\'t say anything except \"Hi, Bye, Thank you!\". Because I didn\'t know English at all. So I tried to only listen for 5 months at the class. It was a difficult time. I wanted to give up every time. I thought that If I had known little English, I would have spoken many words to classmates and teachers. First of all, I want to understand the questions somebody asks me. And then I want to express and speak up my opinion through general expressions in English.
