What does "being anime" do to make it any better?
Think about how specific your request actually is. Considering most anime is adapted from another medium like manga or LNs that means there most likely already needs to be an existing story like this that you won't read because it has to be anime. The likelihood of there being an anime about it is pretty small. "Horror" anime is also notoriously not scary and the amount of it that exists at all is enough to be listed to completion in a youtube video.
Remember that a single fucking country is responsible for this entire medium.
