I think my therapist's approach is similar to your Kashi in that she has said she doesn't see what I deal with as illness, even though it can be pretty extreme under pressure or from triggers (DID) and I will always have to deal with it. She is just more strengths based so doesn't see a benefit in identifying with an illness. It's more that these are symptoms that developed from early life experiences, and not something genetic and maybe that's the difference?

I had a therapist who did see me as having a MI and it was awful. She flat out said, You are very ill. And it was the session she terminated, referring me to someone else (as in, giving me their name, but that was it). It was soul-crushing and I will never forget how that felt. I prefer my therapist's approach, no question.

As far as it being transitory, I can see that being true in my case. The symptoms (depression, anxiety, dissociation) are less problematic when the triggers are identified and I learn to respond. So in that way, it's transitory, BUT, I will always have to do this to some extent so in that way it's not.

I guess I don't really have an answer, except that I tend to agree with Kashi's line of thinking.
