In IFS, you're supposed to accept all of your parts. My T told me that the "protectors" are around for good reasons. They're just doing their job to protect you from getting hurt. I think there's a way to talk to the part without upsetting the protectors but I don't remember how it's done. When I told my T the judges were preventing me from talking about how the teen part felt, she asked me if I could "put the judges down for a minute on the couch next to me." That's a freeing and compassionate way of dealing with them. I don't know if it works in therapy other than IFS, but you can try. But the most important thing is not to judge the judges or the protectors! I hope this makes a little sense.
