Too much lunch

I just went way overboard at lunch. Now I am miserable form being too full, and mad at myself. My closest friend had the gastric sleeve in February of last year, and yet she still gets a full plate of food. That is all bad for me, especially on macaroni and cheese day. She can't eat all her food, so guess who reaches over and finishes it for her. I am so tired now from overeating at lunch, don't know how I am going to get through the rest of my work day, let alone exercise tonight when I get off. Oh Lord please help me, give me supernatural energy and motivation to do the things that still need to be done today. Thank You Jesus.
