I'm so so sorry for your loss Tom, truly there are no words for something so heartbreaking, watching your video reduced me to tears all over again.
To explain - I lost one of my twin Daughters just under two years ago in an RTA, she had only just turned 14. When she passed, part of me went with her and there isn't a waking moment of every day I wish she were still here with us.
Hang in there fella.
