It is indeed strange when you do something that you have done before, but, with different circumstances. I'm sure that it all worked out for you as soon as you got into the things that don't require being concerned about the kids. I adapted to it twice. First when my kids grew up and second after my divorce when I started going solo. It is a big change and requires a little thought about how you feel about things, but, it honestly can be as good as it was early on, just different.
