I'm vaguely in a similar boat, I had developed basically all the ADHD coping strategies and seem to have masked very well. I basically force myself to be organised so I don't for example miss appointments, and not necessarily in a healthy way.
I only realised I had ADHD about a year ago in my 30s. I got the diagnosis in the end, and medications have been helpful though we're still working on finding just the right combination.
If the medications help then that's good, and if not hopefully something else will.
All Blåhaj are valid.
The smolhaj tend to be a bit better stuffed, though the 2nd 100cm I got was also better in that regard.
