I’m fully “out of the closet” about my ADHD and proscribed amphetamine medication. It’s quite refreshing and I’ve personally only received responses that ranged from neutral to positive.
I’ve also noticed that it’s helped other’s around me that are still keeping their diagnosis a secret to see me being comfortable talking about it.
The reason I talk about it is exactly as you say, I think it’s really important to try to destigmatise things like ADHD and ASD in the workplace.
Especially in tech of all places, nobody seems to want to admit that a non-trivial part of the tech industries success is down to it being a field that plays to the strengths of neurodiversity.
To be clear, I’m not criticising you for keeping it to yourself, I totally get it!
Just wanted to provide a voice of reassurance from someone who’s “come out” and living a better life because of it.
