Getting over discouragement

Sorry not sure what board I'm supposed to put this in. I just played elise jg and it was my first time and my bottom lane (lucian and fiora) talked a lot of trash throughout the whole game, saying that I was terrible and that I should uninstall forever. I then proceeded to mute both of them but in the post game it continued and it was a lot worse. Felt so crappy.

What do you all do when you guys get discouraged (from losing streak, bad teammates, etc)?
