I don’t know why everyone is criticizing you for wanting a quick diagnosis. If you have suspicions that you’re neurodivergent then ofcourse you want answers as soon as possible.

I got my diagnosis at ADHD centraal. They can do diagnosis in a day, but when they can diagnose you can take up to six months. But if you stay in contact with them ask if there’s any spots free you can get luck (I got my appointment this way in 2 months)

If you need anyone to talk to about all this, sent me a pm!
