My dad and I lost my mum the same way nearly four years ago now. If you need a shoulder any time (well an intercontinental phone call) just drop me a pm.
OMB - I personally got solace from posting here when I lost 2 members of my family in the US, I hope too that you benefit from the wishes from the forum.
My heartfelt condolences to you and the rest of her friends that loved her so much.
