Prion Disease Fear?
gojomo: It sounds as if you've developed an irrational obsession and phobia about this disease.Make sure you talk to your psychotherapist and trusted friends/family about the level of distress this is causing you. They can help restore rational balance to your thought, and may help you recognize other contributing causes for your fearful mood -- other emotional stresses, substance/medication issues, etc. -- that you can address one by one.
