What I actually did for a living was different from this, but as my course of study, this was covered in college.
I worked with mentally ******** adults and children, some of whom had been abused. It is very hard to seperate your emotions from the job. Sometimes these kids get a raw deal, and in some situations nothing you can do will fix it. I did enjoy it and it was rewarding teaching them something new. That is what you would do with kids, help them, protect them and work with a team to teach new behaviors, because (my college speaking here) they come to you so very broken.
If it is a group home situation you would say, consult for, there are teenagers there who only know manipulation, and qutie honestly ( college practicum speaking now) they are attention starved, and will go to extremes to get that attention if they are in a group home. Sexually abused kids, on average seek out sex, try suicide, drugs, and will do anything to get it. You have to be strong and place boundries on your own personal space with these kids. You have to be firm, but caring. You will be working with the kids as a caseworker, and training the adults who care for them too. Before the flames come I was talking about kids who are placed there after other options have been exhausted. I am giving a view into the hardest cases.
In any case I would find it very rewarding, but I choose not to do it, even though it interests me, because I just get so mad at the situation and feel helpless to fix it some of the time. I want to focus on my kids during thier childhood, but when they leave the house I would love to do that kind of work again!
