Thanks everyone for your kind replies, they have been helping me.

And Dave thanks for the link to the website re: stages of grief.

Somebody said it was normal to not believe my dog is dead. But is it normal to not feel upset about it too? I mean I think about the things we have done together and I start to cry a bit, but I don't feel truly unhappy about it, so although I can feel sad about him, I don't feel that sad, I thought I would be far more upset than I am. I feel gloomy all day now, the usual depression feeling that I had finally got over, but I don't feel it because of Dexter, even though I know he is gone and I can't do anything about it. I just don't feel upset about him in general unless I think of a particularly touching thing we did when he was younger. Is this normal, to not feel much sadness?
