Headache...

Last night, I had a headache and my eyes were hurt. I think it might be overuse of my eyes. I went to library to search some information about travel English because I wanted to finish my homework as soon as possible. Don't put off till tomorrow what should be done today. After I had lunch, I felt my eyes pain. Gradually, I got a headache. Although that is not a news to me, I often have such bad situation. Every time I went to see the doctor and the doctor said "you're just too tired." The doctor didin't exmine any strange problem in my eyes. If the doctor say so, I just get enough rest. Ha...I can't stop working of my eyes but I hope there is no problem of my eyes.
