Sounds like you need more practice, perhaps other champs in your arsenal, and a little more patience. I by no means am pro, but I've learned a lot the last year I've off-and-on played (specifically the last few months that I've tried out other champs and lanes). I've gotten a lot better. I've carried wins and weaker players. I've lost a lot. It's an even mix. But there's a reason some in our pool are paid to play, and when you watch their vids/streams, you can see them carry bad teams.
So experiment away! You might just find a new anti-meta. I was the same way of thinking as you once, so I decided to play Teemo support. Not the most viable, but dear God was it fun, and when it worked, it worked hard. Tankmo top was also pretty cool.
But in the end, you'll be back to the meta if you plan to win. And the better you get, the better your team should get as well (so they say).
