Lin - I am so sorry about the loss of your son and his wife! For certain you don't need this to add to the stress. I too used to be a nurse - I think most of us hav the - it is what it is - mentality but then we get up and prepare to do battle. I had my mom and step dad with me throughout ... I could feel my mom in particular with me. Your son will be at your side watching out if you need it... Hopefully you won't. Take care.
