How to send a text message to the teacher when taking leave in the group?

Class teacher, I am sick and my parents are very worried. Let me ask for leave and take me to the doctor. I'll be fine soon, and I'll try my best to catch up on my studies. Goodbye, class teacher.

Puppy love.

Dear head teacher, hello, I have a lot of troubles. I know you try to correct your homework every day, and your head is bigger than ours, but I can't find any good ideas. I have no confidence in mathematics at all, and I feel that mathematicians are particularly annoying, but other students get full marks, which is terrible. Not earthly, right? My father says every day that you look at others, but their intelligence is also inherited, and that I am lazy, but I will be very tired when I grow up.
