Most T's go through therapy of their own, its supposed to be part of the process.

As for me I know my pdoc has OC thought cycles, and I know this because of the way he ended sentence for me when I was describing what I was going through. No one who hadn't been through it, would have used the words he used.
But I don't ask, because I don't care, has no bearing on his treatment.
Everybody's experience of depression and anxiety and trauma is so individual that I find there is nothing to be gained by comparing war wounds.
I have often found those who have experienced it assembly know how you feel....They don't, they know how they felt.
At least those with no experience understand that they don't know. Mostly.
