The inner critic becomes toxic when you have no awareness of how this part of our ego is impacting us and the relationships you have with others.

When you have no awareness of your inner critic, that demeaning voice within you will come out in the way you treat family, friends and colleagues. People may experience you as impatient, angry, abusive, loud, intolerant and uncaring. The trouble is when you get to this place you will have no awareness that anything is wrong.
