Unexpected surge of grief

I lost my dad to stage 4 metastatic bladder cancer 2 months ago. From diagnosis (on father’s day) to him passing away was 5 weeks. Lots of NHS failures along the way also contributed to the situation. I thought I was managing my grief, especially as I have 15 and 17 year old daughters who I have to navigate through this too, but I have absolutely fallen to pieces over the last few days. I feel lost, broken, confused, angry and unsure how to even begin to move forwards. Any help or guidance would be much appreciated. Thank you.

I am only a week and a bit into this awful journey so I don’t have experience to share I’m afraid. However I also have teenage children and know how it feels trying to manage your own feelings whilst having others to think about. To be honest I think I’ve been pretty rubbish at managing that so far. I’ve cried very openly quite a bit, spent a lot of time just doing nothing and got frustrated with them when they’ve been self absorbed. I know this is a rough time for them too but they are dealing with it very matter of factly which is hard to see. I’d quite like to be by myself for the time being but that just isn’t possible.
