Are you... gatekeeping a mental illness you don't have? :)
I'm a software engineer with ADHD. I've been diagnosed by doctors, psychologists, and even imagery (SPECT scans). I work at a big tech company, and I'm very senior and well paid.
They're totally compatible. It's not easy, but by adulthood most of us have a lot of skills to compensate, and sometimes medication.
I'd liken focus with my ADHD to holding a firehouse - it's actually incredibly powerful, but difficult to control.
What evidence do you have to demonstrate the power of your invention? Is it usable, can you build a business around it and sell it?
I've got a lot of experience w/ the technology stacks used by big tech companies - a lot of time the value of things is not the idea but the execution and implementation.
You've already got context, know the stack, whatever.
They might be happy to have a known contributor solve some problem or project for them.
