Dnestor try something...

look at your keyboard that you are typing on to make a post.

now pick one letter. Im going to pick the letter E.

now imagine that E had a mouth and voice and could talk what would it say if I asked it questions...

Me... Hi letter E do you have a name

now Im imagining the letter E is answering me...

E ... my name is just E.

now Im imagining me talking to just E

Me ... its nice to meet you Just E how are you feeling

now Im imagining Just E is telling me what their feeling / Emotion is

E... Im a bit angry and tired.

now Im imagining asking Just E another question

Me .... Just E what do you look like?

now Im imagining Just E answering...

E... If I could be any object I would say I look like an Elephant sitting on their behind.

this is what go inside in IFS means. you sit quietly and notice what parts (thoughts, emotions, images) are there and then ask the IFS questions.

IFS for some people with DID, Schizophrenia and other mental disorders where there is Chatter and alters works the same way.

my suggestion is do what your therapist wants you to do.
