Being undiagnosed is Schrödinger's diagnosis
I'm a physics student at the University of Cambridge and I am living with an undiagnosed illness (which I call Pete).
For those not familiar with Schrodinger's cat, its a thought experiment used in understanding quantum mechanics. If you have a box with a cat in it and release a poison into the box that has a 50% chance of killing the cat and no way of knowing if the cat is dead without opening the box and checking then as long as the box is closed the cat is in a superposition of states where it is both dead and alive.
Being undiagnosed is Schrödinger's diagnosis because it is both
Curable and incurable Cancer and bengin Something serious and not Treatable and untreatable Progressive and constant That scary thing you read about and something much less sinister because you don't know which until someone actually takes the time to investigate properly and diagnose you. It's scary and it's lonely.
