What the hell do you want from me RIOT?!

I have almost had it...i really have. I was almost done with this game after i was bronze 4 after spending 3 weeks strait (my Christmas vacation) getting to silver 4. But some very, what i thought were helpful posts, about how "If you really were silver 4, youll get there again," and the "youll be silver 4 again in no time, just play carries" convinced me to keep trying...IT'S BULLSHIT! Getting out of bronze is nothing but luck of the draw! No skill is required, you just have to hope your team has fewer trolls and unskilled players than the other! I was finally playing games where we would group, take objectives, engage in team fights together, actually have a laning phase! and now its like all the work i put in during my free time is worth FUCKING NOTHING because im right back where i started 6 weeks ago! Someone tell me what to do! because apparently the 100ish hours of cs practice, and the uncountable number of hours watching pros play so i can learn strategy from them, and the 100's of hours just playing normals isn't enough to get gold, let alone silver! The output reward) is not equaling the input (ALL MY FREE TIME) and i honestly dont know what to fucking do. im not going to keep doing this "win one lose one" bullshit i had to go thought the first time to get out of bronze.

I should point out, the reason i played so much over the break was because im taking 19 HOURS of classes this semester and i knew i wouldnt have enough time to grind to silver then so i did it over the break....but SURPRISE SURPRISE, GUESS THAT PLAN DIDNT FUCKING WORK!
