sick of this game

check my match history and you will confirm in my past ranked games that my fault was on two of them and the other i played decently well and still lost i cant get the logic that the taric trolls and leaves his adc clears my jungle and never presses ult in one game not even once not even mentioning his items it isnt worth it how i am suppose to win with a 0/15 taric in my game with zero assists and this one teammates doesnt happen in one game or two but in the majority of my games i cant play 4v5 every game another example is mf in my graves game she was 7/16 i think and run it down with her ult she always miss her ult or ult in the opposite direction the last game i went with my main vayne and i got to say me and lb carried the game but we still lost cause in the early game i didnt have a supp literally the teemo was afking in the bush waiting for the right moment to press q while i was poked by sona and jinx thus i wasnt able to farm very well but i got a lead with my lee sin the game continues with a fed lb oneshoting everyone we played 3v5 me lb and lee sin rene and teemo were just bad rene was just stealing kills and farm even thought he was bad at it with a negative kda and teemo was afk farming the whole game i have the worst luck of all time i am ready to kill myself i cry all the time
