LA,
I still get angry thinking about that doctor asking you why you have so many kids.
You and hubby are so amazing to have all your babies and take little children who need love as your own.

It's just wonderful and I know you love them as much as they love you.
The stress factor seems to play such a big role when doctor's don't know what is wrong with us. I had it from several Neuro's and one Cardio and a couple of PCP's over my long adventure with MS. They just don't want to admit they don't know so they make us question our sanity.
Thankfully, I now have a Neuro, PCP and Cardiologist that I trust completely. If I don't like a doctor, I move on the the next and it eventually works out.
Hang in there and you will find a good doctor. Just keep looking and don't settle if you can't feel comfortable and communicate.
