I think - they didn't think they could survive the grief... So instead of allowing the grief to really hit, they sucked themselves into a project. It is totally understandable and it's a great thing to do. Keep your mind busy. You can't break if you're busy doing other things and setting up a charity is no easy feat. They are going to be busy constantly, always thinking up ideas, going to meetings, doing research, networking with other people. I wish them all the best and I really hope they smash it and do everything they say they will do. I know a girl who's kid has cancer and is always at the children's hospital getting chemo & having check ups.
Imagine being told your child is riddled with cancer, giving her chemo which is essentially poison and then watching it ravish your kid... and if you're one of the unlucky ones, watch them die. It's brutal and I'd want to die along with her if it was me. The only way I could keep sane & stop myself from drowning is to keep myself busy. Charity for these, and for thenursemum its her shop she wants to do. It's gotta be better than drowning in grief and having thoughts of suicide just so everything can stop.
I do find Ashley comes across quite "me me me" but I guess if he wasnt, we wouldnt know who he is as he would never have been casted to go on reality tv.
