I took a quick look at your past 20 ranked games. Looks like you're top in 5 of them, all 5 times as Irelia. Here's the breakdown:
4/4/11, but your team has no adc and no support. Predictably, this was a loss. There's little you can do when this happens.
4/3/2, your team's adc was 13/6/7 and your support was 7/4/16. Enemy Jinx was 3/8/1 with 26 cs. Meanwhile, your lane opponent was 10/4/2 with more farm than anyone on either team.
6/6/6, your adc 16/9/6 compared to the enemy adc's 3/10/6. But the enemy Fiora was 16/4/12 and they won.
5/3/1, your adc 4/0/5, your sup 5/1/6, your mid 5/0/4.
9/0/2, your adc 5/3/7, your sup 1/3/9, your mid 4/2/7.
I'd say you have plenty of games where your mid and/or bot do just fine, and you have plenty of games where you don't win your lane. Rather than trying to alter your playstyle to account for the fact that your other lanes will always lose, you should understand that your lanes are going to lose half the time and win half the time. You should simply try to improve at every aspect of the game, rather than attempting to fill the shoes of the mythological Ugh-Bronze-Team-So-Heavy hypercarry.
