I don't understand how MM can say grief is taboo. It is true that some people might not know how to react/support a friend when he/she/they suffer a loss but I don't think that's taboo. I think that is just discomfort.
And for her to say there are no resources - Uh, I don't think she's right. When my mother died last year we were offered grief support for a year (without cost) from her hospice care plus our church also offered grief support. Same thing when my father died this year. We, as a family, also had "the ear" of friends and other family to talk, share, laugh, and cry about them.
It seems to me as you said, Coffeewinewater, MM is wallowing in grief.
