League isn't fun anymore

Like It was fun in all when I didn't care but now that I care and my friends are silver it sucks. I can play a bad game and lose, but when I play a good game, I lose. It's like if I play a good game I still lose kp for it, it's like why should I even try inless there team is terrible, there is no way I can win. My friends stopped udoing with me because in the bronze elo they can't take it anymore. I can't play lee sin because he isn't good enough to 1v5, and I can't jungle because when all 3 lanes get shit on I can't help them all and the lanes I do gank the other 2 lanes whine, I can't play this game anymore
