Hypochondriasis
The one and only disease a hypochondriac DOESN'T think they have.
Me: Ugh man I have a headache... I think I might have an aneurysm that's about to burst! Or maybe brain cancer!
Friend: All that is very unlikely, but what you do have is hypochondriasis.
Me: NO, I'M TELLING YOU, I HAVE ALL THE SYMPTOMS OF AN ANEURYSM, AND MOST OF THE SYMPTOMS OF BRAIN CANCER!!
