It is useful to be around people who have overcome their grief already.When Mom died dad went to grief counseling at the senior center, for several years. After a point I think it hurt him more than helped. After awhile they should have helped him put his grief away instead of keeping it raw.
To some extent I blame them in part for him ending up prematurely in a nursing home.
Like you said Manonthestreet it is useless and counter-productive to be around others who are continually grieving and have not gotten over it yet.
