@juergen_hubert Ahh you'll get there 
For 50 years I thought there was no way I could be autistic, but when mentioning my level 2 autistic son in therapy the therapist looked at me and said "have you ever thought about your own autistic traits?"
When I came back the next time I thanked her for the weeks of revelations I'd just had, when sooo many things throughout my life suddenly got their explanations.
(Being GenX and thus forced to learn how to mask well I would never be able to get diagnosed, so no actually-tag here though)
