Terrible rank after good provisionals

I am so freaking pissed off that after trying my hardest for 10 games having won 7 out of the 10 feeling good about my ranking I get placed in bronze 5. BRONZE 5!!! WTF COME ON LIKE FR YOU HAVE TO KIDDING ME. Its not like I was carried I was usually one of if not the strongest players on my team and was a key reason to our victory and this is how it turns its great to hear about riot balancing the game and the champions but how about you balance ranked itself its not like getting placed lower is influencing me to play more its making me want to throw in the bag and teleport out of summoners rift please just fix it and fix it quick
