How to feel hopeless in this game, play your promos

I play my G4 promos, matched against 2 plat game think i'm in promos to plat or something then on the other hand 2 games i get top 2 worst jungler and adc in my life. I know the logic behind a hard match in promos to test my skills, but that damn shit test my patience with this game, my luck with my team mates and test a low gold player against low plat player.
