Some deal with it better than others do. Some cover it up better. Fear can be a motivation for controlling others. We control people we are afraid of losing. In doing so we bring about the very situation we dread.
Possessive love can sometimes seem like hatred and often leads to it.
The true self is beyond ego. I notice how problems start when I talk about my fears to those involved in them. My face reflects back unhappily in the mirror of their eyes. Fear is contagious and damaging. I need to think before I express the feelings it inspires.
