Balance? What balance?

So, I just got to silver 5 and I've been trying to climb higher in the division, but, every game that I play, it's a lopsided match with players from silver/gold division, or, some spineless smurfing queers that have no business playing the game against my team of all bronze and silver, usually unranked last season (like myself), and it's a landslide ass whooping usually 2-3 times the kills (at the least) to the other team. I've also noticed that when I win, I gain 10 LP, and when I lose, I lose 26 LP. I'm starting to think that I'm wasting time on this game because it takes 3 wins to make up for 1 loss. That's not even a grind, it flat out makes no sense, at all. Is the game trying to tell me that this is where I belong? If that's the case, I will uninstall and find something else to play that is fair. I can't get a decent team 9 out of 10 matches and the other teams are always stacked while I start off good in my lane while the others on my team feed out of control, refuse to respond to map pings, or, play off of objectives. Any Riot employees care to explain why this is happening to me?
