Stress making me want to eat and eat

I'm sorry you have to deal with a sick animal. I'm in a similar boat. My fiance's cat has stopped eating. I have to assist-feed her with a feeding syringe several times a day. We need to get her to gain weight so we can get her into the vet without the stress killing her because of how frail she has gotten. I just want her to get better, which is stressful, but I know that eating a bunch won't help her, so I keep the urge to binge away with that thought. Last year, I went through the same thing with my fiance's other cat, who unfortunately passed away. Last year, I stress ate and gained 10ish lbs, so I'm not doing that again.

Just take care of her the best way you can and remember that stress-eating will not make her better and it's only a temporary good feeling. Afterwards you will feel just as crappy as you do now. Or if you must eat, snack on something healthy.
