Relatable Autism Struggle?

I’m the most social bastard alive when it comes to cute fluffy animals(yes, I do have one-sided conversations with any cat or dog that I see :,3 plz don’t judge), but my brain immediately forgets that skill whenever another human being tries to approach me. I can’t tell if it’s just the neurodivergence(and possible undiagnosed personality disorder) speaking or my usual disinterest with the concept of human socializing as a whole. Uh yeah, that’s about it.
