I mean the "worry about everything, consider all possible variables" kind. 

I become obsessed with solving or identifying the problem or *what could go wrong*, even when it's issues way out of my expertise. 

Examples: 

* my health (panic WebMD searches) 
* appliances that break or go wrong
* issues with my car
* anything else that could cause danger

The worst thing is when my stressed-out research is proven correct. 

I feel like I'm living in fear and need these inconveniences to stop happening so that my mind can rest. I think I'm smart and cautious, but that is also making me scared of a lot of things.
