Fear becomes clearer when you ask exactly what outcome it believes it is preventing.

Fear is usually vague on purpose, which is what makes it so heavy. Ask it directly what it thinks would happen, and it either produces something specific that can be addressed or reveals that it has been running on atmosphere. Both answers help. The vague version cannot be argued with or prepared for; the specific version can be examined, planned around, and often survived on paper before it ever arrives.

Write down the actual outcome the fear is trying to prevent, in one plain sentence. Then ask how likely it is, what you would do if it happened, and whether you would still be standing afterward. Fear shrinks noticeably once it has to be concrete.
