英语摔伤请假条

I had an accident on the way back home from school.My bike was broken but I wasn't hurt seriously.So I have to ask for a few days off according to the doctor said.Then I'll catch up the courses after I am recovered.

请问你是需要自己请假还是给“他”请假啊？我翻译的是自己请假哦。

Dear Teacher X,

I am writing to ask for a few days of sick leave.
On my way home yesterday, I was involved in an accident. My bike was badly damaged by a car. Fortunately I only suffered a minor injury. My doctor said that I needed to rest for a few days. I will be at school as soon as I am recovered. Could you please let me kow what I can do at home in these few days so that I won't be too far behind? I promise I'll do everything to catch up with the class. Thank you very much for your help.
Your student,
