Match making and balancing out MMR between team.

I have been having trouble having to getting matched up with unranked or players who only played about a month. I am seriously sick of this. What the f%%% do i do? Like I am so f***ing annoied and want to smash the screen. I have done nothing wrong and I try to give my team a advice and it turns out to be being toxic to them for some reason. I really can't deal with this. My mental state have gone too over normal and i have high blood pressure at young age. i can't quit the game considering how much i spent my money on this game. What can i do? or how am i suppose to carry as 1/2/1 ?
