I can understand how you feel. I had a strong fear of authority from events in my childhood. And, I have felt anxiety around my managers to a point I would avoid them. Something changed in my last job. My manager in that job pushed me so much that I reached a point where my only defense to the pressure was to stop caring anymore. When I started to get stressed by management, I would tell myself "I don't care...I am going to do what I can do and that is enough". I stopped caring what they thought of me; I stopped caring that they had expectations of me; I stopped caring if they judged me as good or bad. It seems like it has helped me see them as less authoritative. By not treating them like an authority, they are less threatening to me. I still try to do a good job to keep employed, but I decided I don't care about their position and control. I treat them like they are just another employee. I am not sure it is the right approach, but it is helping me.
