OMG I HATE IT SO MUCH, MAKE IT STOP!

I've been violently coughing all day, like hacking my lungs out to the point where I am physically doubled over until I stop. Then I'm left in a heap of cough tears with a sore throat. I feel like my throat is going to turn inside out every single time, and I am constantly in fear that I'm going to puke all over myself. Please tell me there is an end in sight, I am so horribly miserable and all of the water, tea, and drugs are not helping.
