When I first read your post about the divorce being final, I said an extra prayer because I had a feeling you were going to struggle a bit....not because I'm so smart, but because I've been through a similar situation. We focus so much on one aspect (your divorce) and all your energy has gone into getting it over with.
Now, like so many wise people above me have said, your emotions are catching up with you. Remember, you're perfectly entitled to your feelings. If we don't deal with them when they come, they have a tendency to come back and bite us in the a$$. Personally, I would be very angry, too, if I were in your shoes. I'm not even a mom, but I know how mom's are when someone hurts their kids.
You're doing great, and I hope you can take a little time for you to get through this.
Hugs and prayers!
