thats terrible , im so sorry, all you can do is be there for her. And let her know how sad you are too. There is no point hiding it, dont hold it all in and try deal with the emotion when your alone. Just give her your love its the best thing you can offer. Tell her you are there for her.
But look after yourself, talk to others as much as you need to about it.
What happens to our loved ones affects us.
Xxxxxxxxxx i hope that you can all bond together in this time and realise no matter how much has been lost, no matter waht the strugggle you have each other, that there is love worth more than material goods.
