In his book The Good Psychologist, Noam Schpancer talks about the importance of stressing that a part of you feels a certain way, rather than the whole of you feeling that way. This empowers the part(s) that don't feel that way to be able to help the part(s) that do, what Internal Family Systems might refer to as the Self.

Even though I'm terrified of this pain, I accept how I feel (or a part of me is terrified -- what age is this part?)
Even though I just can't feel this pain, it scares me too much, that's ok (or it scares a part of me, what age is the part that is scared -- what age is the part that feels the pain?)
