have to speak English

Many Japanese left here. I am so sad, and a little nervous, so that I have to speak English all the time. But It's good for my English, I know.
Today my friend, Joanne came to my house to use my laptop, because she don't have her laptop, and had to sent E-mail to her family. She brought some icecream to me, so we ate the icecream together, and talked about many things in English. We enjoyed that time. I really relieved that I could tell her what I want to tell.
I have to speak English. That the reason I'm here for.
