Anyone feel like helping?

This champion has the most beautiful design, the most wonderful voice acting, and the most simplistic back story. I adore this champion to near hell. I want to main this wonderfully beautiful champion. Alas, I am but a humble support main, losing more often than I win. I had figured enough practice would help me... but... after reaching m6 and 1 S rank away from M7, I still have no prowess with this champion. Last game the enemy jungle was so well warded I couldn't set foot without the enemy collapsing on me. The same game I got counter picked by a full lethality who hounded me everywhere i went and stole every mark. My after getting killed in jungle 2 times my team refused to help me in gank, so i failed to get any more marks than 4... even with boosted mark system. Rengar hit me for 1000 damage every q not counting his ultimate. I failed everywhere i went. my team hounded in on my jungle, I could not counter jungle. I could not gank. I could not farm lane. I failed that game so bad, i went 2/10/6. Kindred's new "buff" is something I do enjoy. It's the first in a long time that they have gotten attention they so desprately needed, and it gives them prowess in jungle. But I can never deal enough damage. I can never hit harder than any enemy jungle. And I never get any back up from my team.

If I am to get better, I need advice. I beseech you. assist me in my endeavor. I wish to make a seemingly useless champion feel like god!
