I tell myself that it's just a game but in clutch situations my hands start shaking, blood presure rises and I feel something wet in my pants. As a result I cant shoot straight or think logicaly. What do i do?

I (16M) play in the Mumbai server and today I were in a Bronze Competitive Lobby. There was a Phoenix in out team who opens up the game saying that He'll carry us, but in the 6th round starts swearing at me for no apparent reason at all "...
