Correção de texto "Dear Doctor..."

Dear Doctor House,

I’m writing this letter because I’ve felt so sick since yesterday and I don’t know what’s happening with me. I’ve got a very sore throat and because it I can’t breathe very well. In this moment, my body temperature is 39.5 degrees Celsius and I’ve got a terrible headache and earache. I think is flu but I don’t have sure. So Doctor House, Can you tell me what is my problem and what I have to do to feel better?

Thank you !
