Advice on Jungling

Hi everyone, I've had a problem practice in normals as jungle and I can't figure out what the best solution to the problem is. The problem is that my teams int way too hard. I've tried switching up from playing more objective focused, lane ganking focused, pure farming focused, and it's always the same - all 3 lanes feed. Hard 0-5 level so feeding and there doesn't seem to be anything I can do to make them stop. Even in games where i hard camp a lane and get them flash at level 3, come back around get first blood, they still lose lane 1 v 1. What have you all found helpful when the matchmaking system has given you bad RNG? What strategy have you found most helpful with dealing with players who insist on dueling when behind? Truly I appreciate any advice. Thanks!
