Question about ranking up

So recently I managed to climb from silver 4 to silver 2 80lp. Ever since i hit that I have lost more or less every game. My experience in those games is that all of them had people that flamed and were just really tilted, which was unlike the games that i was winning. Also, matchmaking is putting me against plat players while my team has unranked people and vice versa. Can someone explain what this mm is? Or do I just need to take a break from this game to untilt?
