There is no formal word for a fear of running. A fear of walking
is called stasibasiphobia. A fear of running out of reading
material is called abibiliophobia.
What does it mean to be tortured with your phobia?
I would say that your phobia would torture you if you keep
running up against it as your life progresses. Lost opportunities,
walking away from good things, delaying what you need to do may all
be signs of avoidance due to a phobia.
