I need help to get out of silver 2

Hello folks.

I need some advices from higher elo junglers seriously. As someone who managed to hit Platinum in no time in the past as a jungle main I am really struggling right now. I really regret playing ranked provisionals during preseason 8 so I wasted my Plat MMR and as intended, got placed in Gold just few days before season 8 actually started so.......somehow system didnt count my old MMR and placed me in Silver 3 after that preseason Gold. Managet to get out of silver 3 in just a few games and than....hell of a silver 2 lol. I cant carry, theres no way. I would be happy if you go check my match history and tell me whats going on. If you take a look at almost every defeat there my KDA was somewhat reasonable for games where I had/ 1/13 Talliah mid, 1/14 Vayne top, 1/14 Jinx ADC, 17/17 Twitch ADC, 0/11 Kled top, and, as I recall 0/12 Xin Zhao top, last game I had Tristana with something like 4/12 lol, tnx God we won that because of Akali and me.

Is there any way to help your teammates other than taking objectives and ganking? I feel like I am lost. It doesnt matter if I take 4 drakes in a row on my own, it doesnt matter if i go 12/2/10 as Shyvana, someone, someone has to be 0/15 and the game is just pointless from that very moment. In ladt 30 games I dont remember more than 2 matches that I lost with teammates having reasonable KDA.

My mmr is fine, i am above 50% win rate, losing 15, getting 22+ lp but, its either a 0/15 teammate when I lose or an even and somewhat close game when I win. I feel like i have to work really hard to maintain the lead while in the other hand theres literally nothing I can do to prevent someone from dying 15 times.

I just need a tip, nothing else. I am desperate. I am literally affraid to start the game because i always feel like somdone is gonna fck up with 0/15. No jokes, check out my MH.
