Hi Julie,
I'm happy for you. I wonder if it might be easier on your son and stepson because they don't live with you. I mean, they will have time to think about what is so wrong with it all. If they lived with you, it would be too overwhelming. Just a thought.
A good first step, though. And a good reason for others to not murder themselves (Isabelle). It's one thing to not have access to your children NOW, but that will pass. You can't take advantage of that future opportunity if you're not here to do so.
