Dealing with the death of soloq (serious inquiry)

I'm not even gonna touch the issue of "how do we determine ranking if premades and solo people are on the same ladder" and "rito i totally keep playin with teams halp pl0x", and i'm not here to hate on dynamic queue. And honestly maybe i'm exaggerating, but i'm frustrated and not sure what to do.

I'm one of those people who hasnt really committed to a role, but instead is good at a handful of champs across roles. And i'm struggling a bit, both on ladder and with this game.

It started off as just dealing with the uncertainty in solo q drafting. You didnt always get the role you wanted, but you could at least get a champ you liked (or were just good at). I used to dream about ranked teambuilder, or being on a team where you just have ONE role you specialize in, but i came accustomed to the way things worked, and even came to like it. For example, most mm i just cant figure out, just dont work with my playstyle. But there are a lot of CHAMPS that do. And it was kinda nice being fourth or fifth and being able to choose your champ AND ROLE at the same time based on bans and what everyone else had picked already. I started seeing solo q as that place of flexibility. This wild west where you sacrifice stability in order to do whatever you want. Quite distinct from ranked 5v5s imo.

Now, even when im queuing up by myself, i feel like im queuing up for ranked 5v5s, only its with random people. If thats how solo q was supposed to feel, well, it didnt for me. And now im starting to wonder i have to finally "settle" on two roles and really commit. But the problem is i spent all my preseason learning champs i was interested in and liked a lot and was doing well in, not even thinking this change to solo q would have this much of a negative impact on me. Im not confident in any role other than mid now, cause theres no other role i have a wide enough champ pool with high proficiency. I feel like my only option is to stop playing ranked for a while and practice a whole bunch of "in meta" champs in a single role other than mid. But that sounds so.... not fun.

I guess what i'm asking is.... is this really it? Is this really my only option? How have y'all been dealing with this role-centric change? Please no bully, i'm not trying to complain, i just really need some support. :/

EDIT: Advice from anyone is alright, but i'd def prefer it from people who empathize
