im only as good as the people i play with.

so i got 14 day'ed on this account. i was overly negative in most of my games. the ban is over but i dont wanna risk being permaed on the account so i made a new account.. but now im just matching with silver+ players that just completely rape me. my gameplay has seriously dulled but i dont think it matters, if i get into a game and theres a plat on my team; im uninstalling because it makes the game pretty much impossible to win with where im at currently. THIS IS IN NORMS. im level 25 and for the past 40 or so games ive lost 90% of them. its no longer fun and im actually getting stressed out over it. any tips?
