Have a bad cold

I have been ill for a week.
Last Monday, I was suffered from headache suddenly. I went to ICU Clinic, and lay in bed. My temperature reached 37.5°C. I was absent from ARW class and Aikido Club.
Tuesday, my temperature was still high. I see doctor and take rest till Wednesday.
Thursday and Friday, I went to ICU, but Friday’s activity is too hard and I relapse into coughing. It continues now. I am really tired of this situation.
