My post was very much a tl;dr - it's been like 7 years since I started realizing something was wrong at work. I upped and left a really good job for something simpler, somehow ended up in the same role a year later (LMAO) but somewhere that made me yearn for the problems of the previous job. ADHD "diagnosis" 3 years ago (GP gave me meds), autism/ADHD diagnosis via assessment process last year.
Vaugeness was less of an issue at the old job because roles and responsibilities were more clearly defined. Here they are not, and the scope of my responsibility is so much more.
Just mentioning that it's been a hell of a journey, mostly so others who read it won't beat themselves up for taking long to figure it out.
