What I wouldn't give to take this disease away!
Beloved49 is right, maybe he should seek a counselors aid. :) It can't hurt!
You seem concerned and I just thought sharing a little of what I know as a partial caregiver to my Mom might help you.
My Mother has been coping with myelofibrosis for almost 3 years. Transfusions and constant Dr. visits cramp her style. She is on some heavy painkillers for her legs...but she found a bright side to the narcotics: they help her sleep through the night! Even through nightsweats! She always seems to find something positive. But that's just the kind of person she is. Your father is sorting things out for himself I am sure. I have heard of patients "turning off" toward the ones they are the closest to. I know my Mom has to absorb all the information and treatments in her own time and I have seen her blow off close family members that pick at her for too much information and constantly question her. That is simply the best way she can cope. So we certainly give her space and don't push her if we don't want our calls to get screened! LOL She has to see her specialist and have lab work done every two weeks now. On top of checking into the hospital for transfusions at least once a month. So she might get one full week out of each month that she has no appointments!! Not to mention daily leg pain that is excruciating at times. So she is sick of thinking about it 24/7.
She enjoys her good days and I mean she is up and gone until she can't go any more. But unfortunately there are other days that I talk to her and she is stranded at home and called off work because she has to sit perfectly still through a 3 hour nosebleed. The day after Christmas, she had a nosebleed for 8 hours straight, followed by a two day gig in the hospital. :( On those days she is down and taking care of herself. But she does spend time with her hubby and talk to us on the phone, even for a few minutes... even when her legs are killing her. That's the sad reminder that my Mom's time is precious and finite and nothing should ever be taken for granted. Anyway, I hope your Dad warms up to those nearest to him soon. You must have patience and understanding with him though. Whenever I am not sure about the way things are going for my Mother, or what to do I just ask myself "What would she be doing for me, if this situation were reversed?"
Take care now and let me know about your Dad! I know you struggle with this on a daily basis in your own way. FYI, if you want to be involved more, just organize a blood drive and have everyone typed to see if there is a match for your dad. I did this and my Mom was touched by the number of volunteers she got! You could also join the national bone marrow donor program.
