Harry Potter and the demons in his head

This story is about Harry Potter having a mental illness.

"If we interpret the story as Harry's fantasy, then the Dursleys are Harry's real parents, and the Potters are imaginary. The Durselys either can't cope with the increasingly-delusional boy living with them, or perhaps they are merely abusive, and it's the abuse that's making him delusional. In any event, the parent-figures constantly mistreat him, favor the brother, and inflict endless cruelty and humiliation on him. One day, Harry snaps, and Dudley (who is really Harry's brother) is severely injured, in a way requiring repeated hospital treatments. (In the delusion, Harry imagines that a pig's tail is magically grown from Dudley's buttocks.) As a result of this incident, Harry is taken away to a "special school." This comes from a theory from a reddit user called, u/Mr_Broomstick nine years ago, but I decided to take it up a level and bring this theory to life via story. I hope you enjoy it.
