(not sure if this question belongs here, let me know if there's a better stack exchange category for it and I will happily take it down)
I'm currently working on a story that involves a main character who's biggest flaw is her self-doubt, low self-esteem or lack of self-confidence. Whatever you want to call it. I'm thinking that she will show this deep self-doubt by pushing others away because she fears they'll learn too much about her and end up not liking her, an easy thing for her to believe if she doesn't like herself.
Does anyone know of good examples of characters like this? I know there are plenty out there but I'm having trouble thinking of many. I just want to look at and think about what a character like this does to slowly push the ones she loves away so that I can hopefully find some inspiration in how my character might do this throughout the novel.
