Does anyone have a way to deal with insensitive doctors?

my son is not well. he is super thin and can't swallow good he has seen top specialist for his problem. today i had taken him to a new nutritionist. she made it seem as if it was my fault saying if he doesn't gain weight he will have to be hooked up to feeding tubes. i'm just so angry and hurt right now. she said it as though i could help it. she just has no idea the worry that me and my family go through trying to get him well. they want him on stupid pediasure that i agreed to put him on again even though it made him so constipated that he was rushed to the emergency room. it's just an onward battle. and i'm already scared for my son. so why are the docs soooo insensitive and point the finger at me. well it seemed that way. as if i'm not doing my best to get the weight on. i can't tell you how much of an effort we are doing to get him well. i just felt really hurt by the doc insensitivity to not watch her mouth. i'm in the hospital at least once every 2 months trying to get a hold on
