What to do when you win you go 6 0 early game but enemy bot laner is 20 0 at 10 min

This post is made out of pure frustration but i'm asking a legit question

I can't seem to win 2 games in a row to rank up, it's legit impossible, i win lane every time but every other lane for my past 5 games can't win and that's fine ,but they int and they don't even get banned at 2 24 kda, how am i suppose to have the mental, i'm actually going insane, like please help me

What champ top lane can kill fed adcs with a frontline, i play xin zhao top / illaoi exclusively but any smolder fed with a yuumi or jinx with a frontline is impossible to get past i can't solo carry.
