Good morning,
Great advice already! It is a shock to receive news like this. Life often likes to throw curve balls at us. I think I won't add to the list of books or resources here, as there are many.
But as mentioned before, having a counsellor will help, and also meditation, sitting with the emotion and acknowledge it. Lay down and treat your emotion like your little girl and comfort her.
I like this song I like to hear when I am feeling blue: Darling by beatiful chorus. it really soothes me.
Hang in there Rose1988
