@Dinoswearunderpants you are not alone. However every grief journey is unique.
I completely understand. 7weeks since my mum passed away very suddenly. 3 weeks since the funeral.
For 5 weeks I did nothing but organise funeral, deal with coroner, banks, solicitors, life insurance, etc etc etc.
A week after the funeral I felt "ok", like great I could go back to work tommorow right (busy teaching job). We went to pick up mums ashes from the funeral home, comforted dad.
When I got home the grief hit me like a bullet train. I couldn't move off the sofa for two hours, felt numb.
It's got harder some days, but I fully expected it would hit me after the funeral as the shock wore off and I believe I am now in the early stages of true grief.
I have been walking alot, giving myself time to think.
I felt angry today, felt as though I'd taken huge steps back, but the small steps forwards will take time.
It's never going to "go away" maybe just more bearable?
I have listened to some of the Grief cast podcasts (usually not a podcast listener) and they have helped hugely!!
Best wishes
