IFS model shows that we have many parts but that they are led by our one Self, whose job is to lead our parts in harmony. Many times my T has said "that's just one part of you" or "your parts are leading the show".

The child part wants to sit in T's lap and have her hold me. I feel like she's a child. The teenage part has a crush on my T. That's another part. My T says the Self accepts all of my parts and doesn't judge them.

Maybe you could look up Internal Family Systems for readings about the subject.

Another example: If you, for instance, want to lose weight. I do. One part of me would like to be thinner and healthier and is motivated to watch what I eat. However, another part doesn't care and just wants to satisfy her cravings for sweets. My T would work with the parts separately. We haven't done it about eating, but we could.

I know IFS isn't for everyone. I never thought I would like it or that it would help me. But it did.
