Oh, I'm so sorry you're going through this too 😔 Sending you so much love and support. Our wonderful dads were/are gifts to us, but it makes the pain of losing them agonising.
I hope tomorrow goes as well as it can for you. My sister had to take a beta blocker to get through the funeral. I was so underslept that I genuinely don't know how I got through the day, but somehow we just do. In a way I'm glad the funeral memories are a bit fuzzy, as I want to remember my dad alive and animated more than clearly remember seeing the coffin a few feet away from me etc. It was recorded, and I might watch it one day, but it's too soon. I feel like I was cosplaying at being at my dad's funeral, as it can't possibly have been real, as my dad must surely still be alive. I can't believe what has happened honestly.
I'm from an Irish/Northern Irish family, though I live in England, and culturally funerals happen much sooner there; so it was such a whirlwind organising it. I've been in denial since I got back to GB really.
I'm so sorry that you've also lost your mum, and being an only child must make this an extra lonely time for you. I hope you have some wonderful supportive friends and other family round you. But, whatever the case, I'm so pleased you have this board to post on. I only just discovered this thread, and I already feel so grateful for it.
I hope you can get some good sleep and rest (easier said than done I know) and I hope tomorrow goes as well as it possibly can, and that it gives you some peace.
The pain is just unbearable isn't it. What I'd give for another day with my dad - you probably feel similar.
You take loads of care xx
