Well that's not a fun way to spend Thanksgiving :(. I'm sure that was very frustrating and upsetting. Since it's the weekend do you think you could still get together with your family to go shopping and out to eat or maybe cook a few favorite dishes to eat at home tonight or tomorrow and rent some Christmas movies?
I'm sure it's very frustrating for your mom as well. Speaking from my own perspective as a Lyme patient with a severe case, I know when I'm ruining things for other people due to symptoms popping up. That's part of the reason I like to be alone all the time. I'm also known for pushing through things and not backing down off my protocol even if it's making me sick.
Does your mom have a PICC line? It's unusual that she goes in for IV antibiotics. Usually you can do them yourself at home.
