My $0.02 as a response to several comments I read in this thread:
I was diagnosed with ADHD in my 40s and got Concerta. My belief is that ADHD is not a disease, nor a disability (even though it acts like one very frequently) and in fact there is evidence that ADHD is an important part of our evolution as a species.
The problem(s) mostly relies with the modern way of life and what is expected from the society at large. In that context I try to feel ok when I daydream while I have countless of boring things to take care of as I totally feel ok when I hyperfocus in a creative endeavor.
The meds are just a tool that I use no more than two times per week in order to take better care of myself and others. It is not a therapy and it's not me. I believe that Sensitive Rejection Dysphoria is very real for people like us, but the worst version of it is when you reject yourself because you are different and you try hard to be someone else.
A solution (given that management and the team at large understands how this situation is a problem) is to combine the open office with some deep work rooms or if there are no rooms, sound proof pods (eg. from Framery)
