Grief for the long term...

Hello hospice nurses...
I have a question.

Do you know of any good websites on how to help someone deal with grief that is year (decades) old? I am not asking for medical advice but this relates to a friend of mine right now - his mom died when he was 12, he had to take on a really strong caregiver role and because of things happening in his life right now he is grieving for his mom in ways he never did as a child. I have done peds hospice for a year, taken ELNEC and I know what to say (sort of) in the immediate period, but am totally lost when it comes to the level of pain I am seeing with my friend. I know there is a word for what he is experiancing, would it be disenfranchised?

Any thoughts would be appreciated!
