So your stuck in your league here's some advice

Choose a mid, bot yeah because these lanes can easily get fed and turn the game during early game before mid game starts, but generally speaking mid mage bot adc, they are squishy I say do this play a jungler, now I carry with Warwick and that's building him as a tank the last 5 games I've won with him I did if not the most damage on my team very damn close to it and I'm almost always taking the most damage having some of the most kills on my team if my team sucks I carry them. A jungler is a strong pick but you can't die early the point of this game that people haven't seem to grasp it's simple don't die don't tower jump if you know for a fact you can't get the kill and if you do 1-1 especially if you have a bounty isn't really an even trade cuz you had full health that mofo probably didn't. You can move around help another lane steal a camp from enemy jungler bait the laner out a little play safe you are low elo for a reason you are no pro so don't play the hero.
