Is Blodwen still with us? Sorry but it could read as though her loved ones have had their last visit.
I am wondering why ask the question - are loved ones upset at being shut out? I can understand wanting to be alone or just with professionals, even if you are dying, you may feel that you have to be thinking of the loved ones needs rather than the other way round, when perhaps you may want to relax and be mindful of your last moments. There are one or two people I would not mind having sitting there, saying nothing, just in companionable silence, but would hate all the family members to be gathered round watching. On the other hand, they might feel offended or upset at being pushed away from my last moments, and carry that with them for the rest of their life, whereas, once I am dead, my last few moments on earth will hardly matter to me anymore.
If you are lucky enough to be in a hospice at the end, you could let the staff know how you feel, they will be used to dealing with it in a gentke kindly, manner.
