Hello Lily, I've only just seen your thread and add my heartfelt condolences to you.
My daughter was killed in a car crash 7 years ago; she was 21. Life DOES go on, and you will enjoy life again, but in a different way from before. You have to start living this new life, with two sons and a heart load of lovely memories.
It was the anniversary of my DD's death last week. DH (her stepdad) and I went to the grave and just sat on the bench near her for 20 minutes, not saying anything. The sun came out and warmed us, and we cried silently. It was so draining, the rest of the day was a write-off.
BUT, most of the time things are fine; we just get on with our lives as we would have done before - there is no option really. We take our pleasures where we can, and try not to stress about things. My younger daughter is living life to the full, determined not to waste a moment, and I love spending as much time as I can with her. All I can say is, hang on in there, it is such early days, and you are still in a state of shock. I'd say it was a good year before I started thinking and acting 'normally' again. Be very kind to yourself, and try to accept that life will never be the same again, but it can be fun and fulfilling.
