I am not a professional, but I think I can relate - I've kind of been thinking the same thing.
For me, I don't think it really matters if I have an official diagnosis. I don't have an external incentive to get one and it won't change how I act. I also don't really bring it up to anyone, unprompted. Mostly because other people probably don't give a shit and likely didn't even think about it. They'll just think I'm weird, more often than not.
Hazel is adorable!
