8 ranked game lose streak

here's my op.gg: http://na.op.gg/summoner/userName=rumbleyoyo

i really only fed or didnt do well in the first 15 minutes in like 1 or 2 game, but because one lane ints i end of losing everything. legit just went from gold 5 promos to silver 2 75 lp because my bot lane fed in every single match. riot needs to do something about get matched up with actual teamates for real. is there anything i can do to like solo carry or something because trying to play a champion that would benefit the team as a tank or support champ is never going to work if my team doesnt do anything.
