Are you thinking Theme or Title? I think you really already have your theme:Girls discussing important life issues. Not knowing the content makes it hard to come up with an idea.
Titling it is another story. Perhaps this will help?
Use common denominators between them all. Are they all teens? Are they single mothers? Do they live in the same neighborhood? Is this documentary a cry for help for the situation or just informational?
A decent title could be "It happens here everyday" "Take a walk in my shoes" "Through my eyes" or " through Her eyes" Hope this helps.
