Pirate that's really eloquent, you have hit the nail on the head. Work is work. Life is what you actually live and feel from day to day.
A year ago tomorrow my beloved dog died of a stupid mistake after an operation, he was 5. I had a lot of support from the Doghouse posters on Mumsnet, just as well as I completely lost it. I have lost both parents very young, and my best friend died the previous year, but I have never experienced loss like it in my life. It has impacted on every part of my life and our whole family. None of us could understand it. If someone had told me before he died that we would be like this I would have thought they were raving mad. Luckily I work from home, but I have been through every stage of deep depression, complicated grief, am unable to sleep (so been sleep deprived for well over a year including his illness), have been ill most of the time since he died, I could go on. I remember the day after he died reading a post on a pet bereavement forum about a woman who was still upset 3 months after her dog died and I thought please god don't let me be like her, how stupid etc. (I also thought please don't let me feel like this for 3 months but in fact it was going to be a lot lot longer).
My DD was then 11, she held our dog in her arms for over 3 hours after he died, and has slept with his blanket every night since, both DDs have had panic attacks and nightmares. Even our vet came round with flowers and cards, he wrote a letter to DDs about it, why he became a vet and how he had grieved for his animals etc.
So based on all this I thought right, lets find out why, why is this happening to us? Initially I used the Blue cross Pet bereavement service (brilliant). Then I spent months researching pet bereavement and read many articles from researchers including recent studies about how losing a pet affect us so badly because of their innocence, their trust and unselfish support they give to us, I read quotes on the death of (mostly) dogs from Aristotle, Shakespeare and Dickens, Roy Hattersley's account of his dog Buster and was moved to choking tears by Sue Perkins' "Letter to Pickle". And finally, I knew that mad as it was, I wasn't alone and that in fact, my feelings are normal. Destructive yes, but not madness, not some personal failing, but just pain and grief. I've planted a garden for him, made a memorial, am writing about him etc. To be honest I feel a bit sick sharing this with you lot as its very personal and so raw.
Just because you lack the empathy and insight to understand that other people feel differently to you OP doesn't make stuff unfair, but it does make you unreasonable. However if it makes you feel better about yourself then yes maybe she should take annual leave.
