How would a girl between the ages of 11 and 17 act if she had suffered neglect, abuse and abandonment issues?

I think how the girl acts over her traumatic experiences depends on her resiliency. I know some who have also some tragedies in life but they are really resilient and perceives life as a blessing and bad experiences as challenges, also for them life is too short to be spent in tears, depression and anxiety. I think if you can see the girl's behavior whether she continues her good emotional and cognitive functioning, then she could be resilient.
