Though it does seem a little disheartening to hear this, unfortunately that is most promotion games even in higher ranks like gold, plat, diamond.... I hear a lot of the same thing. If it isnt someone feeding then leaving, it is people lowkey trying to lose the game anyways and especially if the game is past 15 minutes and THEY are not doing decent.... they will spam surrender and try to int and make the game end instead of trying to win and making it end sooner.
Fortunately, until plat, you will get the "you didnt win your promos so here is a free win" and it does help a bit. Not a ton, but it means you need 2 losses or 1 win, rather than 2 losses or 2 wins. Ranked is a marathon and not a sprint... the faster you try to climb the more things stand in your way. Keep trying to go at a steady pace and you will get to your destination and not feel overburdened.
Also, though it does not help with feeders and inters etc directly.... listen to some music while playing. It will help keep your mind on the game more than the chat and will help keep your mood leveled. If you want an example of the music I listen to.... theres this here. https://www.youtube.com/playlist?list=PLDnVnJEVyh_yyVkw9uoOGN7B2NNa-oPHs and while not everyone listens to the same things, this is just my example.
