I Have A Fever

Today, I felt a little uncomfortable when I had dinner at my grandmother's house. My head was a little dizzy and soft. Dad took my temperature and found that I had a fever of 38.5 degrees Celsius. Everyone was worried and immediately took me to the hospital.

At the hospital, the doctor checked my throat and said it was a little red. She gave me some medicine and asked me to get more rest. I felt a little cool after taking the medicine, and my body felt more comfortable. The doctor also recommended me to drink plenty of water to help my body recover.

It was a challenging time for me, but I learned a lot from the experience. I realized that I need to take care of my health and get enough sleep to avoid getting sick again. I hope to return to school soon and continue my studies.
