How can I express my condolences to a man who has just finished surgery? She is my mother's sister (not her own), and I'm not very good at talking. Please send a model essay and a short message.

If it were my relatives and friends, it would be like this: Aunt, your operation was very successful, which made us all feel infinitely gratified. After the operation, due to weak body, you should recuperate slowly, be sure to be in a happy mood, face the disease optimistically, and maintain a good attitude is very important for your future recovery. We will all pay attention to you, visit you and wish you a speedy recovery. I hope I can help you.
