Therapist implied I have something like DID

She said dissociativeness is a sliding scale and I have things that fit the role of alts. I said I knew what they were doing and could usually feel when they came to the front she wasn't sure it was fully blown DID. I should add, she's just a therapist and said I'd need to speak to someone who's trained in that field to tell me I'd it is or isn't DID.

Is this similar to other people? Is it worth persuing a new/alternative diagnosis?
