As the Beatles sang long ago, "Yesterday, all my troubles seem so far away ... Oh I believe in yesterday ..."
I'd met a married couple years ago who were both threatening suicide. Due to the pains they're experiencing in their marriage.
How could they be lifted out of that?
We used nostalgia, among others, during sessions. Visioning. Revisiting their past.
I asked them to think of their love theme song, the times they first met, the long-ago dates they had when they felt most loving and romantic towards each other.
Both also reminisced about the many wacky, fun times they had with their children when they were growing up.
Fortunately, their nostalgia trip remedied enough their joint suicidality!
We're then able to work together on the deeper issues of their relationship.
