I am very glad to hear that you have recovered from your illness.
We were all very worried about you. And now with your relatives and friends' nurturing and warm caring, your disease is recovering. And those who know you are very glad that you are now recovering.
You are a brave man. I was proud to be your friends. I hope that you will soon be completely healthy.
Thanks for your sympathy with full of encouraging. I am now taking time out to recover shortly afterward. I believe that I would be discharged, and can see you soon. I miss you so much. Thanks for the encouragement and support. I'm more confident now. I promise that you will see a healthy me.
Thank you for your letter. During this period of time, owing to the friends' encouragement, I feel very warm and also have more courage to fight against disease. Additionally, I am not alone, so I will restore the better. I will cherish my body thus having a energetic and healthy body. Please also take a good rest. I'll have a party to celebrate my recovering this weekend, hoping you can come to our party where everyone could get together.
