Made A Scapgoat Out Of In Ranked?

Why does your team flame someone who either gets caught out once or twice and claim they are "Int Feeding", like seriously. I recently had a game where I admit I wasn't on my best performance but was trying to farm and make an impact. During the game I had what I would call A Troll Support Pick and the player could only flame me for dying once early. Then when my mid laner says "Team?! GO IN!" when I have less than 100 HP and no mana. Yet when I die yet again while trying to get away its my fault. My Troll Support Pick then leaves me to 2v1 in A lane where I am already behind and go top lane. The enemy bot lane leaves, i move up to farm cs, they wrap around and kill me from a combo of slows. As you may guess I get flamed for "Int Feeding". I go back and hug tower, still 2v1 with no help, and get tower dove and die yet again. Yet no one seems to think "man if he had an ACTUAL support to help that didn't leave for top lane it wouldn't be as bad." Got no ganks bot lane, no one really came bot lane to help, they just kept flaming. I try to play safe, try to stay near team and towers, but then they complain that i'm not helping. Again I admit I wasn't doing well, ended 0/5, but that's not how I do in A large majority of my games. Normally I do pretty well. But when i'm getting no help, flamed by A troll support, and being made the reason for us losing when it was a team failure, what am I supposed to do?
