Karen, just be gentle and do eat a little when you can. When we grieve, our bodies respond as if we are actually sick, and so we need to take care of ourselves as if we are. Comforting, soothing , nutritive foods will help you as you grieve.
You will slowly make it through, but try not to push yourself to feel normal. Just grieve. Mourn. I needed an herbal relaxant to get through the sudden shock, and it made a big difference and helped a lot. I used valerian root to try to sleep through the night without waking too much. I am getting a little better but I still feel I am in denial. Being here helps so much. We are animal lovers and we all understand the pain of this loss. It keeps in perspective the courage it takes to love and let go of animals whose lives are so different from our own. Life is fragile and beautiful. Grief is not just pain - Your grief honors Petey's life and love. I send my deepest condolences to you.
