How can i stay calm?

Hi, i have had 3 games in a row( and 15 out of 20 games) where my team was feeding, and it is late at night. So it went like this. I easily won my lane and start to split push i got t2 top and t1 bot. But my team was trolling . Our jg was 1/10 at the end of the game, my bot and mid were missing every spell in every fight. So i got upset and asked the enemy 5 times during the game to report them for feeding/trolling. People think this is toxic apparently as i recently understood. So how can i deal with such conditions and stay calm?
