I very rarely contribute to these threads, but..
see that, well, IMHO, the best advice you can get and the best things you can do just now will seem to be the lamest. You’ll probably want to do SOMETHING but don’t know what, and being desperate to do something will do something that makes things worse. You seem to keeping a lid on things, even if it’s hard to do that – just keep focussed on the kids and what’s best for them – remember this can b a serously frightening and confusing time for them
Other than, what to do next, that’s up to you. Probably nothing for the time being, just get your heard sorted out, once you can see beyond the shock and the pain, you’ll be in a better place to look ahead – which all sounds completely lame, I know
I hope things work out for you
