There’s still a rampant belief that ADHD is a childhood disorder, even among doctors, especially those that don’t specialize in mental health or ADHD. It’s insanely common for women to be diagnosed with depression and/or anxiety when it’s really ADHD, but that idea is dismissed.
A psychiatrist SHOULD be better than your experience with your GP. There are even still some psychs who have this old-school thinking, but just a few. You’re likely to have a different experience with the psych than you had with your GP. And, if you don’t, you can see a different psych.
Hang in there!
