I caught a cold

Oh my god, I caught a cold in today.
I have a runny running nose and a headache.
Maybe cause is that opened window it is because I left the window open.
During the night, I didn't cover pull a quilt myself with a blanket.
I got a some medicine from a friend and I will take the medicine after I eat breakfast.
Maybe My cold might last for is lasting at least one week.

Thanks for your help
