Ranked sucks

Ranked really sucks sometimes =( this is nothing but a vent post but I have been doing VERY well this season in my ranked games so far http://na.op.gg/summoner/userName=ninjablood2 my last 6 ranked games have been losses...i had been at p1 0lp for 5 losses in a row until i demoted and i just can't take it anymore i get my main role i win lane both sidelanes go 0 6 I really just can't understand why people can't play safe....in every game i got mid (got autofilled twice offrole once) i had won lane at the very least and did not feed until both side lanes begin pressureing me... i don't understand i pull all the jg pressure Q.Q I just hate ranked sometimes....
