To be, or not to be?

"Neurosis is the way of avoiding nonbeing by avoiding being" ~ Tillich
​
‘Avoiding nonbeing’? What does that mean to me? Am I afraid of losing my sad little, self-made, identity by embracing the blinding beauty of ‘nonbeing’? Could it be that I can only ‘Be’ by surrendering to ‘nonbeing’. Is my ‘Being’ defined by the eternity of ‘Nonbeing’?
