I think go for it and have a really big cry. You're crying for your lovely doggy and crying for yourself. I can't believe any of it much of the time. I still just want to wake up and find it's a horrible dream.
All my adult life I had a lot of sensation in my right breast (the scene of the crime). I realised on the way home today that I hadn't felt it for over three months and that I never would again. I miss it. I'll get used to it of course but there'll always be a part of me that will be sad.
