I'm really sorry. As bad as it hurts, it does get better. It DOES.
When I was served with the D petition, I flipped out. And someone very wise told me, that while it is a 2nd bomb, "nothing's changed." And, nothing has changed.
Focus on yourself while grieving. It's ok, no, it's necessary, to grieve the loss. But, keep reminding yourself you ARE stronger than this and you WILL get through this a MUCH better and wiser person.
Then, take the steps you need to protect yourself financially.
Hang in there - ONE DAY AT A TIME for a little while.
