I can never win HELP!!

I really do enjoy league at its core, but the loosing is starting to get to me. I always go into a game with confidence as I have a decent pool of champs I can play. The second I check the ranks of the other players in the game, Its silver and bronze on my team. Then on the other team its gold and sometimes even platinum, I mean come on, how are they in the same game as me?? They always crush me in lane and it makes for a really not enjoyable playing experience. Admittedly, I'm probably somewhere in bronze, and I do want to put in the time to learn champions and game sense to improve, but how can I do that versing all better players on the enemy team...all the time!?? All I want is a fun and fair game, I don't care if I end up winning or losing, I just want to have a good time, not tilt, and verse players of my skill with my friends. Any feedback on what to do would be great:/
