In addition to what u/xxmimii said, anxiety is not always reasonable, but that doesn't mean it isn't real or valid. Whether you have a "real reason" to be afraid (or not) is irrelevant, because the fear is there. If you suppress or invalidate an emotion it can fester, and remains unaddressed. Better to acknowledge it, allow yourself to feel what you're feeling, and then try to move forward using whatever coping mechanisms you have developed.
