Is this sensory overload/over stimulation, or something else?

I get the vibe that when I first explained this to my psychiatrist, she concluded overload because she seems to think I have autism,

Could've been the way I explained if,
"Overwhelming, just something in the atmosphere, etc"

But I finally found the perfect way to explain what the feelings are.

It feels like creep core.

Like everything is awesome, but there is this underlying sense of unease,

Cute and adorable things are suddenly somehow creepy and haunting as heck and I'm terrified of things that bring me joy.

Regardless of what it is, I was just wondering if anyone else has had something like this?

Haven't had it in a while,
But damn, it's not great lol.

Yeah yeah, I plan on telling my psychiatrist about this, but I don't see her til the end of September,
So why not blabber on the internet about it? 😂
