Reply to my dean

I would like you to rewrite the draft replying to my dean about a medical withdrawal. I want you to rewrite it as soon as possible. The draft is not in my English, this was translated from Japanese to English by a translator, but the English is so bad that I would like you to correct all sentences to native English sentences, and be polite and not rude to the dean. I do not want you to change the order of sentences as much as possible. If you think it is better if change the order of sentences, please let me know. Also, there may have been some parts of the translation from Japanese to English that were different from what I meant, so I will let you know in the chat if there are any parts that I would like to correct. Please let me know if you do not understand what I want to say to my Dean. If there are sentences that are saying the same thing over and over again, I would like to rephrase them. The message is long, but I want to convey everything I want to say. I would greatly appreciate it if you could give me any advice to be a better reply. I will send you the previous conversations with the dean for help understanding the flow.
