Help getting better (I'm low silver)
So I do not think that I am a remotely good player at all. I have played with some friends that are gold and they tell me I'm terrible but they never offer any help with what I can do to get better so I'm turning to the boards for help. I find that I really often end up feeding 6+ kills because I am such an overly aggressive player. I try to play passive but then I end up going aggressive without even realizing it. I've also been told that my decision making is 'iffy at best'.
Last season I just kind of messed around in ranked and never really tried to climb so my mmr was terrible at the start of this season. This season I've climbed from bronze 5 to silver 4 but now I'm stuck and I'm realizing that if I want to reach my goal of gold that I need to drastically improve at this game.
Any help, tips, tricks, and just general advice is much appreciated!
tl;dr: I'm silver 4. I want to reach gold. Any and all advice is appreciated!

(good all around; good if need some hp and/or building some lifesteal)
(good if you need some extra ad, but still want mr).
