Hi Annette
You are doing something for him Annette,you are being with him,and keeping strong in front of him,this is the time to sit and listen let your dad talk,if he wants to talk about death,do not stop him,just listen,he will not talk about it,if he thinks its going to upset you. It will give you the chance to say anything you need as well.
You are giving your dad the greatest gift you can,that's just being with him:-) many people can not do it.
Just do your best. Love Eve
