Unfair rank games.

Okay, so today I played my first ranked game and got my ass kicked. I mean, it was my first so I didn't expect to win. However, I played another 3 games and lost every single one one of them. Mostly because the whole enemy team was silver or at least a level seven. I just don't see how this is fair because I can't get better if I keep going against people who are already better then me. Also, I'm not trying to make this look like I'm blaming the match making for my loses. Of course I'm going to lose, but I'll never win if I keep going against gold and silver or level seven. Also we will get a gold or silver on our team, but this gold or silver player is paired up with a bunch of bronze player. Its not fair for the player, because of course we're going to be bad. We're bronze. I just really want to get better at league and I just see this matchmaking as a wall I can't climb. I don't know how to win when I'm going against gold and silver players.
