I was 18 when my mum died, after heart surgery. We weren’t expecting it and I was in my first term at uni. Back then, 1989, there was no counselling, it was just expected that you would sort of get on with things so I went back to uni a week after the funeral.
What helped:
being told I must keep talking about my mum (her friend said this to me), I had no idea how important that becomes when someone is no longer with you and so many people avoided the subject.
Being asked how I was feeling occasionally by friends, where I knew they were really giving me the opportunity to talk about how I was feeling. I didn’t have to gloss over everything.
Being in touch with my dad and grandparents frequently by phone, I felt the need to ensure they were ok too.
Having a debrief by our GP, who explained what had happened during the surgery and why the doctors thought she had died (I appreciate this may not apply here).
I helped my sister to sort out my mum’s clothes and stuff, and chose some pieces to keep to remember her. I wore them often during the first year and I still have them 30 years later.
What might have helped more:
Being reassured that no one (including me) would forget my mum. At times I felt that it was almost as if she had never existed, as everyone moved on and/or didn’t talk about her.
Seeing my dad happy again, he was devastated and seemed very lonely too.I found this very difficult, though you can only do your best here obviously. Remember that your dd will have lots of young friends around her who will probably help her to have lots of normal, happy teenage moments. The sadness will come and go and can be exhausting. Home needs to have some lighter moments too.
Counselling would have helped me enormously because I found it very hard to talk about losing my mum. I was very angry at God for taking her away (the vicar said he takes the good ones first). I wasn’t particularly religious but my mum was so I directed my anger here.
Lastly, please reassure your dd that she will never forget her dad, rarely a day goes by without my mum and dad being in my thoughts and that’s always been a great comfort to me.
I’m so sorry you’re all going through this and I hope that’s helped a tiny bit.
