The medical community is one of the most harmful forces for people with ADHD (I know it's not directly related to your comment but I always like to point this out)
Your doctor/psych can really be your worst enemy. They watch their patients suffer horrible outcomes and death, while they do nothing and say "not my problem", and constantly spewing bigotry against people with the condition.
I HAVE to use stress and anxiety to get my work done, and it's incredibly debilitating.
ADHD and anxiety are terrible. The harder you try to focus, the more anxiety you get. It's not something to trivialize like the article does.
