I am sadden to hear about your loss. I know that you did everything possible to give your son the best chance. You had to make a very hard choice, no gilt.
I just got on here for the 1st time in a couple weeks so today is the first time I have seen your posts. I am so sorry for your loss. I can't imagine what you are going through. I never know the right words to say when something like this happens but one thing my Dad said after Mom died a few years back that made me feel a little better was. I guess heaven needed another Angel so God took mine. You and your family are in my prayers.
As parents there's nothing we wouldn't do to save our kids. I know this is a time full of questions and grief. Remember all the good times and know Jesse is being well taken care of now. Be there for your family now....peace be with you.
