I think it fits with anxiety perfectly. You grow up anxious because you didn't feel secure while growing up. You learn that you can feel a little secure if you know everything that is going to happen (control). I remember when I used to be like this. You can learn to let go of this need by increasing your security. I felt more secure by understanding and learning that I can handle any situation that comes up so I don't have to be in control of everything to protect myself. Purging those feelings of insecurity help you feel more secure too. Right now you probably still have a whole collection of these feelings stored away from when you were growing up? If so these feelings are still with you...........
