yes we should all meet up for a cuppa, I would look forward to that 
re the clearing out of your mums stuff to the girls going through this. here's my theory
when my mum died I had 4 weeks to empty her flat, as it was a council property. I thought I couldn't do it and I clung to everything like glue. I was in despair, but I got a sign from my mum and I got it done.
now I have nowhere to visit.
but I said when I left her flat for the last time ever, come and live with me now mum and I sort of feel she did.
I still have a few boxes of her things, but just about everything has gone.
and you know what, I think although its cruel to have to do it so soon, for me it was a blessing, if I had the choice everything of hers would still be there and I'd still be going out there every Sunday and sitting in her chair and crying for her and smelling her everywhere.
I think having that would hold me back more, I'm not really getting anywhere but sitting lost and lonely with all her surroundings would be harder
so what I'm trying to say is you won't feel better once your mums stuff is cleared, but it won't always be there holding you back IYSWIM.
I hope this doesn't sound cruel to anyone, my sibling asked me "do you feel better now" when I told him I'd handed back mums keys to the council, I couldn't believe he meant it, I said "no because I've nowhere to visit now", I know how hearing what I've said is like a dagger to the heart, but I think clearing out things eventually does help the healing process...whatever that is..
sorry if I've offended anyone, this is just my experience, I hadn't a choice in it but for me that was a good thing
