Certain elements of this story ARE indeed real - but you'll not found out what from here.
The disease mentioned here IS a real disease, but there is no fourth type. It is rare & there isn't a cure. I made up the fourth type completely, basing symptoms of what I found online about it.
I am almost constantly making up new stories, so look for them! I always intend to finish what I start, no matter how long it takes to do so. See you in the next story!
