Hi Jackie, I don't think you can fill that hole, and don't try to. I lost my dad last October, he'd had mm for 5 years. I still cry every day, the reason I cry is for my mum, I loved my dad dearly, but the loss for her is heart breaking. We talk everyday about him, the things that made us laugh, the fact he could be so miserable. All the things we loved so much about him. I once asked how do people get through this? I was told, "you have no choice, no matter how you deal with it". This for us as a family was true, so we muddle through each day. I try and see my mum as much as possible, and she has started going out, to a widows group, bingo, anything that gets her interacting. The last 5 years were spent not going out for fear of picking up a cold or something that could have devastating consequences for my dad's immune system. Some days my mum actually rings me to tell me she didn't cry that day. It will take time, maybe try to talk to your girls about how your feeling and how they are coping. Remember this is the price we pay for loving and being loved. Vicky x
