Yes - I'm considering this about myself recently, that I have been undiagnosed ASD and ADHD. Try the test on the ADHD Centre's website, and cross-reference with the Aspie test perhaps. Then if you get positive results, take these to your local (or even the ADHD centre or another nearby private clinician, since the waiting times could be quite long 3-10 years in the UK).
I can definitely relate to those issues and it matches with my yet-unconfirmed, highly suspected case of AuDHD. It's quite common to have both.
I would go with this. If it were me, going along would give me more anxiety. Like being called in to the manager's office so a coworker can apologize to me for something that happened. Somehow you're still a victim at that point.
That analogy happened to me IRL and it was not pleasant.
