I've not managed to read all responses, but hope I can help a little. Im just recovering from an allograft - BMT with my brothers cells. I had Hodgkin's lymphoma - meant to be easy to cure, not so for me but I got there!!
So firstly I've survived a BMT after a lot of chemo!
Do not even consider that any outcome would be anything but positive, yes fine to feel worried but decide that you are going to win, This got me through.
I had 14 weeks in isolation on the haematology wards, I decorated my room, covered the walls in pics from my kids (3&6). Had my iPad - played words with friends against my friends. If wifi a problem I bought a mifi, but the 4g iPad worked fab.
I brought in bedding, had a mattress protector stopped me sweating from the rubber mattress, also had my own pillows and duvet (which had my kids duvet cover as only singles we had).
Ask for sedation for bone marrow biopsies. I too had needle phobias by the end of treatment I'd had two central lines fitted with just a local anaesthetic, I've got over my needle phobia.
Delighted they are letting you see your kids, I wasn't allowed so managed with FaceTime.
In the long run I actually ended up spending more time with my kids as was home a lot when otherwise I'd have been working.
One of the ladies I know from hospital has been cured from ALL with Philadelphia chromosome - with a transplant she's in her 50's.
Any questions please shout! A lot of coping was just getting my head in the right place and pushing on, I also learned to live day to day, I wasn't going anywhere in the next day and I knew that's all I had to worry about. I'm thinking of you
