@popularinthe80s it's condolences from me too and not, if you see what I mean.
I was surprised how much relief I felt when Dad died, I thought I'd feel a bit, but I didn't realise how much the weight of uncertainty was oppressing me. His death allowed me to love him again, which I know sounds illogical given that he was now dead, but my feelings were no longer pulverised by the mass of practical questions and the enormous leaden question mark hanging over us.
I really hope you'll be able to go through all the messy grieving process as well as you can. I think it's lovely that you could come on here and tell us (and show humour re. the dead parent envy).
It is the uncertainty I realise that is the worst. If you told me that my mother had five years, I'd think, right, let's do this and enjoy it and squeeze the best from it. Let's financially plan, let's work out what she gets enjoyment out of, let's have the important conversations.
But I just keep thinking, god it could be up to two decades and I'll be ancient and a husk.
