Letter to mother, about your health

Examination Hall,

My dear Mother,
Thank you very much for your kind letter of April 15. I am, by the grace of God, regaining my lost health and strength day by day. The doctors and the nurses are doing all they can for my speedy recovery. My highest temperature, yesterday, was 99.2 F. I feel that it will come down to normal tomorrow or the day after. Cough has disappeared already. I am taking the medicine regularly. You need not worry at all. My friends and teachers visit me many times a day.
With best regards.
Your loving son,
(Name) X. Y. Z.
