Hi Pam,
I know what you mean about feeling like you are living in a bubble. I had the same feeling myself for a long time after my mum died. The rest of the world goes on as normal and you do the things you need to do, but it doesn't feel real or right. I felt like the world stopped when my mum died and found it odd to see people just going about their business as usual when something so awful (to me at least) had happened. It takes a very long time to come to terms with losing someone and even when you think maybe you are starting to get over it abit, something will happen out of the blue that knocks you for six and you realise maybe you are not getting on with that quite so well as you thought! But you have to keep going at it - if only for the sake of the person you have lost, who will still want the best for you.
I think you can reply to an individual person in 'My messages' if you want to. That message then goes direct to that person and cannot be read on the forum, if that's any help. But reply wherever you like. It is helpful for others to be able to read what's on here too, as not everyone feels confident enough to post a message themselves.
Sending hugs
