as mentioned earlier, no details are expected first session. You can also choose how much you reveal in the forms. I will acknowledge the various abuses, but don't talk about them until I trust the therapist.
Also, I think every intake I have has asked about abuse on the intake form. There was only 1 clinician I didn't have an intake for with, and that one did a longer intake appointment asking all those questions. Even in person I did not give all the details right away (and it was an intake for a trauma group).
Good luck and I hope it goes ok. Try to remember to breathe.
