Are there any benefits from being diagnosed with Autism/ADHD?

I know I'm on the Autism spectrum & most prob ADHD. My family know that I am. My bro & niece are.

So what are the benefits of others knowing?

Does it actually get you anywhere?

Do I need to be diagnosis to prove who I am?

Are there any benefits from being diagnosed?

Is knowing you are Autistic enough?

Would very much like to know your points of views on this & maybe see it from a diff perspective
