An anxious person's life comes with a set of rules, a guidebook on how to survive that is  etched between the neurons of said person's brain.
Each day fits neatly into a schedule, clocked in by the second and placed firmly into a time slot that is fixed and immovable.
Each thought is churned and questioned before finally being spit out.
Each sentence is perfectly manufactured as it has been sent down an assembly line and thoroughly checked before being spoken.
Each situation is analyzed and placed into a pros and cons power struggle before being decided upon.

An anxious person in love is a difficult thing.
Love can't be placed into a box, can't be precise and planned and prepared for.
Love can't be controlled or put into an agenda, can't be narrowed down into a certain time frame or date range.
Love is bigger than any person can hold in their hand. Love can get away, slip through the cracks and get scattered and messy.
An anxious person does not like messy. It makes them anxious.
