Earth, so sorry about your mother. My mother died a few months ago. A wise friend of mine said when her mother died it was like being without a skin for at least a year (as in, sensitive and raw).
The worst comment I had was from a school mum who I thought was quite a good friend, and had even lost her own mother some years ago. I live abroad so had travelled back to the UK when my mother was dying, with my youngest DD, then DH and DS followed us to be with us for the funeral. When we got back to school, this mum asked, 'how was your trip, did you have a good time?' This completely threw me for a second, as I thought perhaps she hadn't heard my news - but then she added, 'Apart from, you know...'
What, apart from watching my mother die and organising her funeral, you mean? Yes, it was a ball.
My siblings and I also found it hard when the first thing anyone would say after we told them the news, was 'How is your father doing?' OK he's old and totally relied on her and in shock, but I felt like shouting, 'What about me? I've lost my mother.'
Another one I hate is when people who are acquaintances rather than good friends say, 'sorry about your mother, how are you?' What am I supposed to say? Either lie and say something glib like, I'm alright. Or spend five minutes telling someone I don't really know about my grieving process and how much pain I'm in. Anyone got any good answers for this one?
