Teammates hold me back

Ive been stuck s1 for 2 days I cant climb out constant tilted flamers or teammates who just flat out suck and end up going 1/6 in lane seriously sad. What a waste of time this game is give me some actual teammates for the love of god ffs i cant stand it . It brings me to tears when all i hear in a fking game is "an ally has been slain" its insane i try my hardest no matter how well i do in lane and try to bring leads somewhere else i always end up getting 2 feeders on my team who so happen to get the say diana or talon fed. Impossible to climb with all these casuals in ranked just had a yas single handedly lose us a game 1/9 kda DASGWAOUTGL ;TOUARGPOIBARE
