I read a review of a book written by a doctor who lost her sister.
The name of the book and author escape me, but one phrase from the book stayed. It was along the lines that Grief is the shadow of love. Grief hurts as much as it needs to.
Having lost both parents, and too many friends I can understand the sentiment in that loose quote.
It's no help to you, opening poster, you are still in the that buggering shadow. In my experience the only way through it, is through it. Still no help, I know.
I felt my Mums death on the first anniversary of her death more than I'd felt when she died. As the oldest child, I was so concerned about my sister, daughter, nephew and niece, I really didn't find time to do my grieving for a year.
Be just as strong as you need to be, let the rest go to hell. Cry if you need to, whatever you feel, let it out when it's right for you
