Translation of Freudenschrei in German-English

Thank you for writting back so quickly. I learned English when I was a kid, because we've always been in England during summer vacation, since my grandma used to live there when she was still alive.
Just last week a friend of mine showed me how to do these special effect, so I was focused about this word. I have been sleeping five hours a night for a week now and I am pretty tired all the time. Hopefully recovery will come soon.
Do not worry, please, all is well here. I find it fascinating how fast you can write texts in foreign languages. I know how hard it is, and I congratulate you. Waiting to your next email.
