Not to gaslight you but sometimes adhd isn’t adhd. My son can’t sit still and is this way. The more I watch it and talk to doctors and reflected on my own memory of youth I realize he’s basically my clone and I have all these symptoms too. Turns out it’s a motor sensory (muscle/balance) issue that he can correct with some occupational therapy and learned coping skills. I developed my own coping skills without a therapist and never really intentionally built my core strength.

Anyways I mention it because if one can focus on selective tasks, like working on a side project, I think adhd is perhaps an easy/lazy diagnosis but maybe not the correct one.
