Insomnia: It is very, very, very rare & is characterized by progressive insomnia associated w/ extreme changes in personality & behavior eventually resulting in dementia & death, usually over the course of a year or two. It's related to mad cow disease & creutzfeldt jakob disease & is caused by accumulation of misfolded prion proteins in the brain. You don't have it.

SFI: In the first stage of Sporadic Fatal Insomnia there may be a decline in cognition and ataxia. Sporadic Fatal Insomnia usually has an older age of onset and a longer life expectancy than Fatal Familial Insomnia.

Anxiety: Isolated symptom is not sufficient to diagnose a disease. As common as anxiety is, sfi is as rare.
