I completely understand what you are going through. I kick myself on a daily basis wondering what I did to cause this. I am a vegetarian ad often wonder if the lack of vitamins and nutritiuon caused it.
Studies show that anen happens in underdeveloped countries where people have poor nutrition.
I have been trying to eat much better, three balanced meals. I can't get myself to eat meat though. It just grosses me out. I am sure he will. My doctors told me the same thing about the organ donation and it frustrtes the hell out of me.
