Grief...of course I'm a counsellor, so I deal with other peoples grief all the time, but it's my own experience, as per usual, that teaches us the most sometimes
My Mum went into a coma, it had felt like we'd already 'lost' her to Alziemers, 'who she was' what we used to talk about felt like such a long time ago - over five years she literally 'slipped' away. It kind of felt like she was the one preparing us for it. She would hate to upset anybody, ever, she was the most unconditional giving, loving mother you could ever wish for.
Of course, that didn't stop us fighting when I was around 14, I had her determination and 'I will do this' strength - but that was just a blip, we remained best of friends from then on. I could have been jealous of others, if I'd been that type, because she collected other 'children' so many other people ended up calling her 'Mum'.
