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 sin.  

God is our protector. Confess the sin and declare.

“He who dwells in the secret place of the Most High Shall abide under the shadow of the Almighty. I will say of the Lord, “He is my refuge and my fortress; My God, in Him I will trust.” Psalm 91:1-2
