In my discussion here I was merely correcting a misconception that IFS can't be used in therapy with people with DID, when indeed it can.

Mostly the OP's post was expressing concern that the parts language the therapist was using might mean the OP had DID. The language of the parts in IFS definitely does not mean the person has DID... but the therapy technique can be used both in people with DID and in people without DID.

OP, can you ask your T about the DID thing if it worries you?
