I'm curious as to why you think this. What do you thing the upright 6/Cups means?
The 6/Cups is sometimes titled: "known joy" meaning something you're comfortable with. Something that reliably makes you happy. To me, an rx of that card would be like....like going to a restaurant you loved as a child and having your favorite dessert from that place only to find it too sweet and cloying for your adult palate. Or you discover some keepsake in your closet, a favorite quilt, for example, that you've long refused to give away...and you suddenly decide, "It's time to give this away."
Or, of course, you meet up with a friend who has always been closer than a sibling to you and always knows how to comfort you and make you laugh...and realize they've changed, or you've changed. And you know that the friendship isn't the same and you have to let them go.
What gave you so much comfort...doesn't any more.
