What Role do I perform best in?

What the title says, I'm not sure what role I perform best in. I have mained mid lane since I started playing the game, so about a year now, and I really enjoy it. But recently I started playing ADC because I know that if I can do well I can carry harder, plus I also enjoy playing ADC. I have climbed pretty far with ADC but I don't know if I should go back to maining mid or not, because I noticed I'm way less consisted with ADC. Like I use Op.gg and Triumph.gg to occasionally look at my performances, and I may have like 3 or 4 Plat 4 lvl games for example, and then something happens where I guess I go on tilt and I'll play like crap for 6 or 7 games in a row. Of course if I go mid I don't always win lane or anything, but I don't recall ever going on losing streaks where I just play terribly for no apparent reason. Anyway I just wanted to know if there was anyway I could tell what role I perform best in somehow :( Also I know im more comfortable with mid because I know most of the matchups, I just dont' know if I'm at a level good enough to ADC effectively yet, so that's kind of why I'm making this, do you think a Gold 5 is even good enough to ADC effectively? Effectively enough to carry at least, without getting spoonfed kills in the early game?
