I'm not an expert by any means but I think there is some controversy around ADHD being a real thing / problem. Thinking a lot about this "problem" you have is most likely just adding fuel to it.

Most people can't handle 30 minutes of meditation, or focusing, or sitting still, or have a hard time not moving during WILD.

Meditation teaches you these things, they are not a requirement, they are skills that you gain through practice. So start with 10 minutes of meditation every day, the key is to do it frequently, not for a long periods and you will get better at it. Same with WILD, which has a lot in common with meditation.
