Do I have AuDHD?

The title is admittedly a bit clickbaity.

A psychiatrist recently confirmed I meet the diagnostic criteria for ADHD & Autism. Firstly, the terminology makes it sound like I don’t have the conditions I just meet the criteria. I’m concerned that I’ve researched the conditions for too long and that I’ve tricked the psychiatrist into giving me a diagnosis. While I do struggle with the symptoms associated with both, I feel my struggles aren’t nearly as bad as someone with just ADHD or ASD. E.g. I live alone and am able to do most things I want to… eventually. Personally the reason I took so long seeking a diagnosis is because I’m an only child and never really had a reference point for “typical” behaviour as a child. Similarly despite being only in my mid-twenties I do not remember a lot of my experiences between 0-9 years old so I cannot reflect on this and understand if what I did would fit the criteria. I also feel if my behaviour as a child was so far from “normal” expected behaviour of other then professional help would have been sought or teachers would’ve commented on this.

I’ve since told my best friend I recieved a diagnosis and she said something along the lines of “childhood trauma leads to symptoms of neurodivergence so many people could meet the criteria”. I don’t think this was from a place of malice at all. But this played further into my imposter syndrome, as most symptoms are part of the normal human experience and it’s the degree to which you are affected, this is challenging for me to compare to a NT person.

Not sure what advice I want, but does anyone else have similar experiences?
