annoying dry cough

I've been dealing with this REALLY annoying dry cough for the past few days and I'm getting at my wit's end. I've gotten such shitty sleep because of it and it's affecting my ability to do my schoolwork  I've tried my inhaler, flonase, drinking more water...UGH!! 

My mom said that I'll need to use a steroid inhaler for the next few days to see if my cough will calm down so hopefully that will work!
