what is your core fear

There is a theory that everyone has only one core fear.Mine has been feeling judged,not acceped or rejected.I was scared that if i have a panic attack people will not accept me and will judge me this led to having panic attack every time i am with people.I fed up and started to allow my self to be judged and embarrassed ,didn t have a panic attack on a while.So whats. your core fear?
