What role should I main?

I've been conflicted in choosing one main role for years now, I always feel like I'm not either enjoying the game or just playing my role ineffectively.

I've hopped in between roles especially ad and mid since they are my most fluent roles how ever I just can find a happy medium with one role, I really want to have one set role and I was hoping for some insight.

Despite how I feel towards the game I honestly want to put my faith in you guys, why you might ask? because I feel like if I have someone else make this hard decision for myself that I won't have a choice and that I can apply myself to said role and just start a whole new learning curve. My goal was to always hit diamond even though I've only peaked at Platinum 2 but that honestly doesn't matter to me anymore.

I want to enjoy the game again, yes I do intend to play ranked eventually but I just want to learn the game over, play a new role and dedicate myself to it and learn the best way I can. I'm really hoping some of you players will read this and reach out to me. Hell I'm open to criticism and definitely want tips.

I'm going to put a pole up, I hope you guys submit to it and choose a roll for me, please add me in game I'm looking for new people to play with on the daily.
