Compassion Fatigue or Secondary PTSD

I was reading an article on Rainbowkids.com today and discovered the term Secondary PTSD. As I did some internet searches on it, I started to realize that this is a sorely understudied and underreported syndrome.

Most of the literature refers to mental health providers, healthcare providers and "first responders." But there is almost no mention of adoptive or foster parents. We deal 24/7 with our adopted kids past trauma, through counseling sessions, through their behavior, through visits to the doctor and dentist, and through their story telling.

I've heard stories come out of my girls mouths that would make the strongest and manliest man cry. As my husband says, its a good thing their birth father is already dead, because otherwise he would hunt him down and kill him for what he put our girls through. Andrew is still considering this action with the birth mom's new husband, who also abused our girls.

I think Andrew and I are both suffering from some degree of this Secondary PTSD, via our girls. We are just handling it in different ways. I am the one who takes the girls to the doctors and dentist, and we both take the girls to the therapist. We see first hand what years of abuse and neglect have done to their minds, bodies, and souls. Their teeth are rotten, they are short due to calcium deficiency, they have parasites, latent TB, horrid scars on their bodies, warts, eye disorders...all on top of serious behavioral and emotional issues.

Sometimes the girls are so upset that we didn't "come get them" sooner. Other times they want to go back to their orphanage (where rules were more flexible and they had more control over their lives).

I feel like crying almost 24 hours a day. I am exhausted mentally and physically. I just want to lay in bed all day. Now, I do suffer from generalized anxiety disorder and secondary depression, but this is above and beyond that. I know this is not "normal" for me. I don't feel attached to the girls, and many times I just don't care about them. I robotically go through the motions, hugging them, making their lunches, getting them ready for school. I thought it was because they are constantly critical of the food I make, even after they picked it out at the Russian food store, or maybe because when Marina doesn't like the clothes we bought, she "runs away" and says that she doesn't want to live with us. But maybe its all this on top of my empathy for them working through their grief. Now that they are in therapy, more of the "stories" are coming out. I feel like a walking zombie most days, always in a state of shock and detachment.

Just wanted to share this as I suspect some other adoptive parents are feeling the same thing. Sometimes once you are aware of the problem, you can work on fixing it, or at least minimizing its effects, right?
