I am sorry, I know how hard that is, I have been through it. I was very honest with my son. I told him I didn't want this and that I was not giving up on us or our family. He still hears that from time to time, it's been 20 months now.
Stay open to conversation and questions with them, they may come up in the next few days. Also, stay honest. Kids are very aware of their parents emotions, it's ok to tell them when you are feeling sad. They don't want to be told stories or kept in the dark, I believe honesty is the healthiest option. It lets them know the emotions they are feeling are normal and ok.
It will be ok, stay their rock
