Dear Ellen, I was very happy and healthy before but recently things have changed a lot. Now I can’t sleep well. As soon as I lie on the bed, I will always think about the things in the day. I tried to sleep, but I just couldn’t. Sometimes I would turn in bed all night. This troubles me a lot. I really don’t know what I should do. Could you help me? Thank you very much. Yours Christina

Dear Christina,
I know how you are feeling now. ______________________________________
