Hello Rene and Welcome to NeuroTalk. I am so sorry your lil Mary is having to go through so much. It's devasting to see our children struggling and not feeling well. *I have a chronically ill grown child*
Helpless is a feeling I felt so much as he was growing up, yet I knew medically, we were doing everything we could. Please take a look around here and make yourself at home. Everyone is here at NT for one reason or another, so the members are compassionate and very friendly.
Hope you can get some answers soon and that Mary is her old self even SOONER.
