1, she may be mentally ill. It's possible. Some mental patients are not obvious, sometimes they can't be seen, but if I get this disease, I am incapable of working.
She suffered great trauma at work before and was afraid to work anywhere again. It is also possible. She is only 19 years old. Maybe something terrible happened in the place where she worked before, which left an indelible shadow on her.
She may have a big conflict with her family. She ran away from home, and at that time she couldn't find a support, and she didn't know how to find a job or make money.
4. Although she is only 19 years old, it is also possible that she is frustrated by emotional problems, so she gives up on herself, doesn't work, doesn't go to school and doesn't want to do anything. She just wants to live every day.
That's all I can think of. I don't believe that she doesn't want to work just because she is lazy. Because I think even the laziest girl in the world can't turn herself into a tramp just because she is lazy. 19 is not young. She needs to eat and dress, and she needs to dress beautifully. Nobody wants to be a beggar. So I think it's not that she doesn't want to make money, but that there is something unresolved in her mind. A teenage girl like her still has a lot of work to do if she wants to find a job, even if she has no education and no work experience. I sincerely hope that local good people can help her and let her return to normal life.
