Losing Promo Series 6 times...

Ok, first i want to say i have tried everything. i solo que a lot and i have been silver 4 in season 4. I have carried most of my won games. This season i was knocked down to Bronze 1 due to a bad placement series. I get paired with really really bad people due to my placements. i get into Bronze 1 and i play a lot trying to reclaim where i should actually be at and the people i get matched up with are so bad i cant stand to play anymore. I am talking about afkers, trolls, and people who have played a champ like my last game with oriana and go 5/15. I have tried so hard to get out of this Hell that the end result is me being knocked down to Bronze 4. Maybe ranked isnt my play style, or where i should be playing. i do really good in the games in win 9/0/6 etc. Then i get terrible people, i get these people about 65% of the time and i lose. This is crazy, as i know deep down i am not a bronze player, i am a silver player, yet due to BS ranking system im screwed. Its getting to the point where i should get another account and try for series again, or do something more drastic. Just some thoughts on this, and why i feel like lol is a terrible game. i try so freaking hard. All my friends keep saying is "just do what youre supposed to do and it will happen" , this of course is total BS. It never happens. Maybe i should get a new account and go from there, any thoughts on this?
