I think The edge of seventeen did a great job in portraying an adolescent struggling with her support group, family, wants, needs and mental state. This is how a person who only knows how to do a thing 1 way struggles with the demands of other people. She was asked for understanding that was scarcely given to her. She became too invested and centered with herself because she felt that if I wouldn't focus on myself no one will. I can relate with the feeling of not being special and having a limited support group and for that support group to be "taken" away, that would feel like sht. It's like being left alone and you feel like you won't have anyone. She said she likes to think that she's the only one with problems because that makes her special probably because she feels that while other people also has problems they also have something else, a carrer, peers, l9ve life but she thinks that she had none of those. Being told that no one likes you, or you're a disappointment is just worse. Because she already tells herself that and deep down she hopes that someone will tell her otherwise but people just keep confirming her insecurities.
