This is how I see it. Fear is a mask and hides something else. In many cases it is powerlesness,.
Once a priest told his small community of rather senior members on a weekday Mass to stop watching the news because they left them powerless,unable to do anything about it,and excessive amount of information they couldn’t t handle.
That I found real and practical.
Also,that when we have not much to do,we tend to fill our minds with uselss, pretzel twisted thoughts,so some pleasant activity if a job isn t possible,or available ,is much better company.
Also serving ,helping people around in little things .
And last but not least,if the fear is too big, one may have to deal with it," peeling off" one by one the layers,until the size of it becomes smaller and more tackable than the big ghost it was.
Recipes that have helped me concretely.
