I often find myself going from being completely relaxed/concentrated on a task, to suddenly fearing that I *may* lose control, or lose my mind. 

It sounds strange, I know, but I’m sure at least a few people with anxiety will resonate with me. 

I don’t have any logical reason to believe I’m gonna lose control or go insane, but I’ll ruminate on the possibility in a ‘what if?’ sort of way. 

I’ll think about it for a while, panic a little or a lot, and then forget about it and carry on with what I’m doing, until it happens again in an indefinite amount of time.
