I have not, but why not start by helping someone else cook, or inviting someone over to help you cook?

It does sound like an unhealthy obsession not an actual cooking problem but if it’s more like you just never did it and have built it up in your head, perhaps taking small steps and seeing that your fears are not fulfilled will deflate them.

I agree you don’t necessarily need to cook, assembling can go a long way, but if you want to cook that is a very good reason to cook!

I will say - as an experienced home cook, shit does (rarely) happen so maybe also taking a kitchen safety class and getting fire suppression equipment would help, practicing what to do if something does happen so you don’t panic at a small fire and let it become a big fire when it would have been easy to put it out.
