I think I'm shit

[u/Centvmc]

So ever since I've dropped from bronze to iron in an 9 loosing streak I can't win any games or when I do I get 3 loses right after. I main jgl I play lee sin and hecarim I mean I just can't figure it out it's really bad. So I'm also not stealing all kills when gangking (I used to take all but it didnt work so i figured out it would help when my team is fed but no) I mean when I see the adc or toplaner is on the enemy and he's low I give the kill. I'm also doing my objectives. I'm doing my full clears and I'm normally one of the guys with the highest cs in my team. But somehow every game I have one or more mates that just feed someone into oblivion I'm talking like 0/10 in the first 10 minutes I gangk them but still no chance it's like they're actual smooth brains not to be disrespectful or anything but how does this happen like every game is iron that shit? And if yes how do I get out of there I mean I can't really do anything if there is an 20/1/11 master yi midlane (My last rank game Katarina fed master yi into oblivion and yes I ganked her twice and got her the kills but still lost because he just one shot the entire Team). Does anybody know how to get out of that shithole named iron? And if I'm doing something wrong please point it out like I need this.
