Dear E,
In the quest to find a slice of sanity after losing you I read scores of books...many filled with positive upbeat streams of butterflies and rainbow bullshit. To say the least most didn't help...I didn't need to hear "you'll get over it...be happy".
The one tome I did find laden with wisdom was C.S. Lewis's "A Grief Observed". He speaks with brutal honesty on his thoughts and feelings while journaling after losing his wife.
"If, as I can't help suspecting, the dead also feel the pains of separation (and this may be one of their purgatorial sufferings), then for both lovers, and for all pairs of lovers without exception, bereavement is a universal and integral part of our experience of love."
Regardless of your stage in grief, I'd recommend you pick up a copy. My library had several or always available at Amazon...
Peace be with you....
