Tami, I'm glad you got to see your mom and visit with the docs and sorry your mom is having such a horrible time with the chemo. Believe it or not, she will recover from all those symptoms eventually, she just needs lots of recovery time and the medical support to get nutrients and hydration until she can keep things down, either through the tube or through her mouth.
I feel sorry for myself some days because I still seem to be having a lot of symptoms (mouth pain, can't take anything orally yet) for someone 3 mos out from radiation but I should be thankful, I think, that my rad. and chemo went as well as it did. I also had the severe neutropenia--that was the most scary to me-- and I wasn't able to finish my full chemo treatment either, but I didn't have some of the other severe symptoms your poor mom is going through. So now I feel grateful, instead of whiny, thanks to your post.
I know that probably doesn't make you feel any better but I guess my opint is there's always something to be grateful for--I'm sure there is in your mom's case too. I'm sure one thing she is grateful for is that she has you to visit and advocate for her!
