> Knowing you have ADHD, childhood trauma, attachment issues, etc. is useless if that knowledge does not enable you to take action or if you don't intend to take action.
That’s not actually true, and misses the point.
Knowing you have ADHD, alone, helps you stop blaming yourself and hating yourself for those things that are caused by the ADHD. It doesn’t excuse it, but understanding that those things aren’t moral failures are a huge deal to those who actually struggle with ADHD.
Moreover, most people with actual undiagnosed ADHD have spent their entire lifetime building coping mechanisms to manage it. Recognizing those does help build others in the future, even if just knowing changes nothing right then.
