help me climb out of bronze :)

hi! i main support and currently i am stuck in bronze. id like to learn how to be better, and climb into at least gold. i main support orianna (i know, its bad) and im looking into trying some new supports, janna, poppy, leona, ect. the problem is, im so used to playing orianna because, if you look at my history, that's all i played. i think i'm okay, but i could be a lot better! let me know if you're willing to help me learn, and reach my goal. :) thanks!
