So sorry for the grief you and your Mum are going through. Is it too painful to talk about your Dad with her at the moment? If not, maybe just reminisce about the happy times, and any humourous moments. Share stories, reminding each other of special times. What I did a week after my Mum's funeral (Tuesday just gone) was lit candles, got all her photos out, and the order of service and played the songs from the funeral,then read aloud a poem I'd written for her. Of course it was upsetting but I'm glad I did it. Maybe you could light a candle for him and just sit quietly, put a memory box/book together or visit a favourite place of his, watch one of his favourite films. Maybe all these suggestions are too much at this stage. I know grief can make you feel very alone. No one has contacted me since the day after Mum's funeral, like its all over and done with now the funeral is past. I'm sure just having you around must be of some comfort for your Mum. Don't be too hard on yourself, this isn't something you can fix and must be incredibly hard for you to not only be going through the emotions of losing Dad yourself but seeing your Mum suffering. I really hope both of you can laugh again some day xxx
