Operation Save Sissy

Hi there, my name is Coco but my family and friends call me Sissy. I am a Chihuahua/Jack Russel mix and I recently turned 10 years old. I was diagnosed with Cushing’s Disease last year which is pretty much a tumor attached to my brain or kidney. That tumor causes an overproduction of hormones that tells me I haven’t gotten enough food or water even when I’ve had more than enough.. After my diagnosis, I had to start taking medication every 12 hours to suppress my hormones. Everything started getting better.. I wasn’t eating too much, wasn’t drinkin excessively and wasn’t having accidents in the house (mom was happy) but as of Friday.. everything started to get worse. I couldn’t stop throwing up and now I’m super tired, I don’t want to do anything. I haven’t eaten since my breakfast Friday morning and spent all day in the emergency on Saturday. My mommy keeps talking to my doctor but they keep telling her they don’t know what’s going on. She spent all her money trying to make me better but now they’re telling her I have to stay at the hospital. Any help you can provide will be appreciated.. I just want to feel better again. Thank you. Love, Sissy
