oh sweetheart, i'm so sorry about your dad - he sounds a lovely person.
it's such early days yet and i know right now you can't ever imagine that raw pain fading. but, give it time, and it will. you'll never 'get over it' but your grief and, more importantly, memories of your dad and what he gave to you/how he brought you up will become part of your life.
my dad died nearly 10 years ago from cancer and, in some ways, it still feels like yesterday. i can really relate to you wanting to 'see' him. me and my sister used to will him to 'visit' us. although my mum once said she felt his presence.
thing is, drivingmecrazy, although we long to just see them "just once more' if that could happen, you'd just want to see them again and again.
i can't give you a time limit when you start hurting less..but that pain is the price of love, isn't it? you're hurting so much because you miss him so much. but, as i said before, that raw pain that feels lie a hard, physical lump in your heart; that agony of waking up each day and it hitting you all over again will fade.
it's lovely that your daughter was so close to him (after dad dying my greatest sadness is he never saw my children, but did hang on for my nephew to be born. he would have been a lovely grandad)
yes, it's hard comforting dd because part of you feels like a child herself who's lost her dad.
it's not the same, i know, but he'll always be part of your family and guiding you - because you can think what he would have advised you/what he would have said/you'll still talk about him and share memories with your family. and you and your daughter are part of him.
you do eventually stop trying to picture his final moments (and it's a comfort he died how he wanted). again i can't put a time limit on it because everyone's different.
but eventually trying to picture his last moments and what he looked like while he was ill, are replaced by memories of when he was well. (often you have dreams, too)
one day, i promise, when you think of him the smiles will come before the tears.
thinking of you
