Feeling Small, unable to get past the authority figure


I always have a feeling that I may not be right and I let another person go past me. Also I have a hard time holding conversations with authority figures. I feel awkward. In my head I am thinking, they are so big, so smart and so well spoken than me. I think I sound kind of abrupt and weird even if I talk. There’s an uneasy feeling around the surroundings at that time. I have been feeling for many many years, and feel like it’s so much engraved in me. Do you have any suggestions on how to get past those feelings?
