It must have been such a relief for your friend to have been able to spare him that but it is sad she lost him at what was already a difficult time
Her DF had been in the dementia home for a long time so his death wasn't a shock. This is going to sound mean but it is hard to write down, in a way it was a relief for my friend and her family because he was getting so bad and it was his time to go.
Not long after he died was when my friend needed the stem cell transplant and has to be isolated for 100 days (30 in hospital and 70 at home).
If he had still been alive at this point then he would have noticed her not visiting for that long and he would not have coped with knowing that his DD was ill, especially because he would not have had the capability to understand it all.
With regards to your hair falling out, different people have different experiences but my friend got annoyed with it falling out in the shower and it upset her every time it happened.
This is going to sound trivial and mean but it was her that said it. She used to get cross about having to unplug the shower drain all the time, really cross about it.
In the end she cut her hair shorter, so it wasn't so dramatic when it all came out.
For work appointments and seeing her father, she wore her wigs but not really otherwise, she wore scarves and hats. She did like to be silly with her wig sometimes and once in a restaurant she put her hand on her head and just took it off and turned it around and started pretending to talk to it.
It sounds silly now but it was funny at the time and it is always good to laugh at yourself.
One thing I would tell you that she would say is that you will be absolutely bombarded with information and advice, some great and some downright awful. You need to do whatever you want to do to feel better, regardless of what other people think.
For example, if you aren't particularly hungry but someone says you must eat, eat what you want, whatever it is. If you feel like having two puddings even though you don't want dinner then do it.
If you feel tired but you have made commitments and you don't feel up to them, cancel them without any concern.
You have got to look after you and only you know how you feel.
It must be quite worrying for you, but you will get through this and come out the other side.
