Oh Jacqueline, like everyone else has said I'm very saddened to read this & cannot imagine how you're feeling. Nothing we say is going to make the pain seem any easier but suffice to say we're all here, always willing to listen, comfort & support. Like others my advice is to take every minute & hour as it comes. This immediate pain will be the hardest to get through. Trust that you will in time remember some wonderful memories without the bottomless pit of grief that you are feeling now.
You adored her and likewise she you. An earthly passing for me is just the ending of 1 chapter and the transcending into another. The loved ones who have passed do see us every day. They know what we're doing in our lives and all about our happy & not so happy times. Often the signs they're around are not the obvious ones we're led to believe to look out for but the more subtle. Like Barb said, a feather. There's also smells, the odd phrase that pops into your head for no reason, a sudden shadow that catches your eye then it's gone & you think you mis-saw something.
Very best love to all those on this thread who have lost loved ones. Milly, I can't imagine how you have come out the other side from what must have been too immense for me to put into words.
I will pray & light a candle for your beloved Mum Jacqueline & ask that you are able to take each baby step. Pain caused by gried if often something we don't "get over", more we learn to live with & accept & feel honoured that we had such amazing beings grace our lives xx.
