Welcome to WP, Helen_L!
I knew nothing about Autism until I was 64. By my 65th birthday I was formally diagnosed as: Autism Spectrum Disorder, Level 1 (Mild) with an extra note that I also satisfied the criteria formerly associated with Asperger's Syndrome. I was delighted by the diagnosis! It explained so much. And I was old enough that the diagnosis wasn't a warning of difficulties ahead but rather a better understanding of the difficulties I had already navigated through.
The diagnosis has had little practical benefit for me. I didn't need any special accommodations at school or work since I've been fully, comfortably retired since I was 56. My friends and family already thought I was "odd" (sometimes other adjectives might be used) so no change there. Even before I got the diagnosis I knew I wanted medical providers to give me stuff in writing...and they seldom did...now I think the diagnosis supports my request for getting stuff in writing...and I still seldom get it.
I admit, though, I got my diagnosis shortly before the COVID Pandemic started so me and my diagnosis haven't gotten out much. But, I've never been very social (now we know why!) and I'm an MBTI INTJ with a strong "I" preference so I rather like being holed up in my COVID bunker (i.e., "home"). Though I do miss fast food...
Two good things about the diagnosis:
<=>1. When my bride bumps up against one of my Aspie traits I can say:
<=>1. <=>"I have a doctor's note for that!"
<=>1. -Though this doesn't amuse her as much as it amuses me.
<=>2. Wrong Planet!
I hope you've found these two online quizzes:
<=>Autism-Spectrum Quotient Test
<=>Aspie-quizRegistering is optional!
They can't give you a formal diagnosis, of course, but they can help you better assess your suspicions.
