How to recover dry cough soon?

What was the last time you were anxious?

Well it is somewhat related to this. Tomorrow is my final rounds for music competition and I'm firm on my decision of performing believer. Many of the piano and keyboard participants were stunned by my performance because its rather difficult to play believer in weighted keys of piano while singing as it is a pretty fast song with chorus of high notes. Well I got a dry throat now and it feels difficult to reach low tone and high tone, even to balance my voice while making aggressive shoulder and elbow moves for piano (a tip to aggregate the audience) It pains my chest to take deep breathes as if someone is squeezing my lungs out. I said to my dad about this and he said to have this homeopathy medication for a smooth throat but it doesn't have any effects yet. I want a quick solution since the finals is tomorrow. I'm avoiding cool things and drinking warm water too. My piano sir said it's fine if I just play the piano but I wanna stand out of the crowd! I ain't giving up. I will sing soomthly even if it hurts and doesn't recovers but for feeling comfortable and look natural I wanna ease this pain.
