Your fears may be the tip of the iceberg, a clue to what you are really worried about. I once knew a young boy who was afraid to go to school. It turned out that the boy was not afraid of going to school but of leaving his grandmother. The young boy had experienced several losses at a young age, first his mother, father, grandfather and most recently his uncle. He convinced himself, if he left his grandmother she would also die.
Are your fears real ( False Evidence Appearing Real) or are they camouflaged to hide the real problem you must face. Ask yourself, why am I really afraid, what is the deeper issue? Just by probing beneath the surface it may offer a clue to the root cause and enable you to expose and confront the fear.
