Kiora Hi, I'm up still too, although not unusual for me. But worry does play it's part too.
I think your aunt will feel better, if you know what I mean, when the funeral is over. I think it's the time between someone dying and the funeral, that sort of limbo status that can be the worst time. It's probably going to have to be a wait and see how things go time. Although if you have to get back for work etc. then you will be concerned about leaving her, it's just natural. Can she not come and stay with you for a bit after your week with her? Or can anyone else take over or at least go round to hers to see how she is and report back to you? She is going to have to come to terms with your dear uncle's passing at some stage, although how when they were together for such a long time, I have no idea. Does she do other things outside the house? Is she part of any groups or church?
Don't feel guilty in cosseting her just now, it's what she needs. And it is upsetting for you to think that she could be sat up and upset without you being there. When is the funeral? Can she join on here and then you could at least private message her and she would feel better for hearing from you if she is up in the night? Or by e mail?
I'm not going to bed just yet so you can reply if you want. X
