If your Dad is ripping out his feeding tub it is never going to work. As much as you want to believe that the dad sitting there is the dad of old that is the one point that says it's not so. I know you are hurting and want your Dad but I just ask that you listen to what the ethics committee tells you since they have come to the same decision that hospice and the other hospital did.
You were absolutely right to inform your siblings. It is up to them what they do with the information but you will always know that you have done what was right
Good luck princess... I hope you find the answers you need and the peace that you want.
