I know how you feel too, but as someone who can get to gold, what i will tell you is that if I could wave a magic wand and put you in gold, you would immediately plummet like a stone , losing 2/3 of your games.
All the people in gold, can get to gold and you can't. How could you be as good as them? I know it's hard to believe, but if you belong in gold you will win 65% - 75% of bronze games.
support is the only exception, but you would still climb.
As adc, if you can carry on a gold level, your win rate will be at the upper end of that.
In one sense, the game is unfair. some people with a lot of experience are actually good, but not good at carrying. They only are slightly better than those around them.
For example, you could be a teemo god and get fed every game, but teemo's carry potential is small.
This is unfair, but if I could put you in a gold account, you wouldn't last long at all.
