I just saw your other post and realized you're on day 1, so I wanted to add some encouragement..... The first day or two aren't easy, but just take it an hour at a time if you have to (or a minute at a time, whatever seems manageable). I lived on this forum during the first days/weeks and it really helped. I let a lot of stuff go, too (housecleaning, etc.). Keep the stress level as low as possible (hard to do with kids, I know). Be good to yourself.
Random thoughts, but they all helped me during those first days....
