Deuce, I'd like to suggest giving this book some time.
Life After Loss: A Practical Guide to Renewing Your Life After Experiencing Major Loss
by Bob Deits
The semester after my father died I took a death and dying class in college. This was one of the required textbooks. It's about grief, (from different sources, such as loss of a parent to loss of a job, including divorce) and working through it. Mine is actually an older edition. I'm sure not much has changed in the new one, except for updating of resources. There are probably divorce specific books out there, but I don't have any experience with those. Maybe someone else has?
I know you are feeling very alone, when you are up to it try to find some grief groups, or divorce groups where you can talk to people. Taking the class helped me immensely, when there was no one else I knew who was going through what I was to talk to.
