Mate, so sorry for your loss. don’t be afraid to be honest with the kids. it’ll be hard but they will be able to take it and i’m sure in time will appreciate being part of this process.
Everything must feel out of your control and up in the air but you will come through this and for the good of you and your kids you will carry on no matter how hard it is.
Just remember you’re not alone and aside from the official lines of support such as posted above you have a whole load of internet strangers here who will be here for you whenever you need it.
don’t be afraid to ask for help, i know in your previous thread there were offers of time and energy for you, those offers will still be there and if it makes this stressful time any easier then please do take us up on what’s available
Sending you a virtual hug x
