Anxiety, fear, and insecurity are caused by more complex reasons. They are not only the influence of life experience from childhood to adulthood but also the things encountered in the social environment are closely related. In addition, the factors of individual character and temperament cause this aspect. If this is the case, the best way is to read books in this area to understand the general psychological development model. It does not necessarily mean that you have to read more professional books and then guide yourself in what to do but from other people’s stories. Get some inspiration, and bring empathy and experience.
