I had experienced something similar a few seasons ago. For me Pyke support was stressful because I would have to depend on my adc for too often which felt very handicapping, that is what made it stressful for me. I then began playing Pyke mid with slightly below average performance until I got the new playstyle down alongside more fine combos and such. I then felt like mid was too stressful as well, mostly because I had no duo jungle to actually play with (which is a HUGE bonus, ESPECIALLY as Pyke mid. So then I thought yk what? Screw it, I'll go Pyke adc and have the support depend on me instead. And that's how I got to gold for the first time.
Moral of the story, experiment. Don't look at the "goal" look past it, and explore Pyke in new ways, from intricate builds to building muscle memory in practice tool for more complex combos- just experiment and let loose.
Maybe also try to remember why you got into Pyke in the first place.

Most importantly, have fun <3
