When someone in the past has controlled you, if Jesus has not healed your heart, then, situations that you perceive control, whether actual or not, you will react. Reactions vary in people; some try to control the situation by cutting people off, and others erupt in anger. Both reactions result from the person trying to protect themselves from being hurt again; this is a self protection is a sin.  

God is your protector. Confess the sin and ask the Lord to heal your heart and deliver you.

“And it shall come to pass, that whosoever shall call on the name of the Lord shall be delivered” Joel 2:32
