Hello there, fellow Aphelios main! From what I've experienced that helped me a lot punching through the shitfest thats called Emerald was pushing waves on mid or if not mid than following an 'Empty lane' rule and going where no one is in the mid game. Itemization is key for ADCs, especially aphelios. My best results were brought by kicking out collector from the build, as it is mostly a bait item or only worth using it in very specific hard stomp scenarios. I rush IE every single game and do some funny business in my runes as I think sorcery doesn't bring that much use with Absolute Focus, Gathering storm and its only for late game. I use Nimbus cloak in sorcery as it is surprisingly fast to react to ganks or engages. I opt to bone plating and unfliching or overgrowth in resolve if there is high rushdown potential in the enemy. For trade heavy lanes or passive lanes i bring triple tonic/boots/cosmic insight/biscuits as they provide some advantages in build or in summs. For Keystones, you can opt between PTA and Conq for phel as Conqueror can be surprisingly good against beefy comps or tank supports in lane. I wouldn't recommend fleet after the nerfs, though. For Itemization, you have to identify the enemies' threats, and buy accordingly. Ex. for heavy AP burst, Maw is great for phel. As for teamfights, I think the best is to let them come to you. You as an ADC don't really have to focus down anybody, just aim to survive and hit what's coming towards you. If someone from their carries mispositions, than its okay to commit for a kill, but you have to reposition afterwards. You can have a priority for pushing waves and destroying towers over participating in teamfights. You would get so much gold funneled into you vs the enemy ad who would participate in a teamfight and gets blown up anyways. With that you would split their team apart and they have to respond to your pressure somehow. Its especially effective if you are behind. I hope my little essay can be of good use to you. If you want to ask about something, then feel free to DM me here.

My wild guess would be for you to find a new main role and experiment with champions and find what you enjoy. You can do this in ranked solo and just play the game for the remainder of the split. I don't think you would have much trouble finding your way out of bronze. And even better, just ignore your rank if thats what causes frustration in you. If you want to learn league, I recommend SkillCapped's YT channel full of free content. It helped me a ton in my fundamentals and macro. Hope this helps. Be well and have fun in your ranked journey!
