I second the above advice that reading about grief more broadly can be helpful. I haven't read the You Can Heal Your Heart book but it sounds promising.

I like the Kubler-Ross book, but more recent research suggests that the "stages" idea of grief shouldn't be taken as literally as it has been (as in you move from one stage to another in a linear fashion). I agree with the critiques as my own experience with grief has neither been in tight stages with the idea of some endpoint, like after you've resolved the last stage you are "done". While I feel like I have made some forward movement in my grief these last few years, I'm not sure that I'll ever be done although my relationship with grief is different now than it was some time ago.
