5 Years Out...

I had surgery June 2002. Had bad first 6 weeks; renal failure, pleural effusion, pneumonia, chest tube and collapsed lung. Prayed to God to get me through this; that I had come this far and want to enjoy life when all surgery problems had passed. He must have heard me. Now, 5 1/2 years later, I have absolutely no appetite. I can go days without eating, don't ever have an urge for anything to eat, nothing sounds good or appealing and don't want to cook much at all. This is not me!! I am losing 2-3 pounds weekly and can't figure out why so many years later, this is happening. Anyone have similar situation?
