Sx 4s, however, still look very much like 4s so they're not exactly a countertype ; but they are kind of what cp6 is to 6, as in they throw themselves into their shame and are constantly in search of what is the missing piece : their main motivation is to find what it is exactly they're missing, and make it their own. They can be extremely possessive and jealous once they feel like they have it, while simultaneously being scared that they're unworthy of having it ; making up for some toxic behaviour when very unhealthy (this is Naranjo's and Chestnut's descriptions of the "mad 4"). They're driven by a desire to counteract their shame, to find the solution to it and to fix it. In that way, since they're going directly in the face of their core emotion, they're counterphobic and as such counter-envy.
