Your match history is pretty much the same as mine lol
But I think the best advice I could give you is that the game is all in your head dude. You have to be smart about it ~ As blunt as that sounds ~ Paying attention to detail will help you a lot ; Map awareness, DPS, ward placement, using the smart ping system, item building, studying the opposing players laning patterns. It all helps toward the final outcome of the game. Sure there are times where you get a team worse than an autistic kid on crystal meth (like %89 of the time cos bronze4lyfe), but if you want to improve YOURSELF as a player then all that stuff helps a lot. But most important of all: HAVE FREAKING FUN WITH THE DAMN GAME. Flaming ruins it for not only you but your teammates. Don't be "that" guy .
