Controllers believe they're in control when they can avoid negative feelings of fear, humiliation and helplessness.
Controllers use anger as a means to remain in power.
They don't easily leave their comfort zone as it makes them weak and unprotected (as it was in childhood)
The Controller
They grew up in a home with no protection, so they had to stand up for themselves.
And they try to feel in control always to make up for the vulnerability they experienced in their childhood from being exposed.
