I received a call from *gasp* the actual doctor at the juvenile facility. I was not expecting to hear from the doctor until next week. He is only there 2 times a month. It has been confirmed that difficult child has the Epstein-Barr virus. That + a change in medications. caused the stomach pain, vomiting, and significant weight loss. I feel better now that I know what it is. It's funny that no matter the age or how frustrated or mad I can be with any of my grown kids when they get sick, I feel the need to nurse them back to health.
