Self, fear of
An irrational fear of oneself, an intense self-fear that is groundless.
Fear of oneself is termed 'autophobia' which comes from two Greek words: 'autos' (self) and 'phobos' (fear) = literally, self-fear, fear of oneself.
'Autos' has given us many English words such as 'automatic' and 'automotive' (self-moving) and 'autonomy' (self-governing).
And 'phobos' has bequeathed us a vast number of phobias such as 'claustrophobia' (fear of closed places) and 'acrophobia' (fear of heights)
