So please keep in mind that I do not know your story. I can only go by what I read on here and have no intention of upsetting you. After reading your last comment about your therapist staying later just to get things out of you sounds like she is putting in more work for your therapy than you (please remember I am not trying to be insulting - simply an observation - and if I am wrong, please correct me).
However, with that in mind, is there any way you would be able to reflect and think of ways to help convey the information to her (writing it down??). My concern is that she is spending all this extra time struggling to 'pulling information', that eventually she will burn out (or something). Perhaps you could help her by trying to find a new approach to share your story? - I mean, maybe it's even telling her you need to work more on rapport with her because you still don't feel safe enough. That way the extra time she is willing to spend with you in session (after however much hard work you two do during) will allow her to help/teach you (always helpful to have more skills/practice) return to baseline and leave feeling comfortable enough to not fear/get anxiety over your upcoming session?
Let me know what you think. It sucks to keep trauma to yourself, especially when you are struggling this much :(
