Sometimes a person can take on fears from other peoples energies.
Have you owned someone's trauma?
Specifically ask your higher self where in your body you are holding the feat, and you may find the locked in energy accessible to heal.
When one finds some sort of fearful thought, it may be well worthwhile for you to stop and consider if you didn't pick up the thought from someone else around your energy.
Blessing the fear with light, love; darkness with light.
