Stomachache

Today I just ate an apple and nuts in the morning. After eating, I suddenly got sick. My stomach was upset whole day. I feel it twisted unragularly. I stayed the bed around 2hours, but it was still painful. I teach my student on weekens,  I had to wake up and went to her house. During the class, I just pushed my stomach. I couldn’t eat anything. But my sister made porridge and gave it to me. I was  really impressive. After I ate it, I became better than before. I don’t know why I got sick today, but I assume that I was too tired. Even though today I couldn’t do my homework all, I will do them tomorrow.
