Going on losing streaks happens everywhere,everytime,to anyone.
There are always the games where you will have a 0/9/0 teammate who doesnt do anything in the game and therefore you lose.
May happen a few games in a row,but in my opinion,its all good,even if you loose,as long as you played well,because if you play ranked,that 1 or maybe even 10 unwinabble games wont matter when you play over 1000 ranked games,or even more.
Bad teammates happen,its low elo and soloq,you cant carry them,and you loose,thats just how it works.
EDIT: i fixed the grammar mistakes,thanks for the corrections,english is not my mother language,sorry.
