Players and Ranks

I finished P5 in season 5 (it isn't anything great, just pointing out so the post makes sense) I am tired of playing games, then everytime I do bad I get told things like these:

"You got carried" "You bought your account" "You see there are bronzes in your elo" "Lucky person that got in that rank"

Why do I have to do good every game? I am tired of these damn comments every single game. I can not get in a normal game and play ADC for example, because I get called a noob, retard, etc etc. I suck at ADC. But somehow I gotta improve at it, and the only way is by playing it. But I can't because I find people like these. It's so damn frustrating. It's like if, because I got to a good rank (well, semingly good) past season I got to carry your damn feeding scores every single time. Then yet I barely see any kind of punishment to any of these players. Seems like queue dodging is more important. Damn it I am so mad. This game is not fun this way. That's it, I just had to let it out somewhere.
