Is it normal to lose your appetite when grieving a pet loss? I have never lost my appetite before like this aside from when my mom was dying from cancer. I couldn’t eat then. The thought of food was unappealing. Which is really unusual for me because I always have an appetite. The thought of food makes me nauseous right now. I have all my favorite foods in the house and none of it is even remotely appealing to me, I don’t even feel like eating and haven’t felt very hungry.
