earthmama, I am glad you had that conversation with your T about calling and emailing. I hope it was reassuring to get clarity on that. Your T sounds very supportive.
I also want to agree with chaotic13. There is not one optimal speed for therapy. I don't think you are necessarily going too fast. There is no timetable that says you can't do X, Y, or Z in therapy before you have been there 3 months, 6 months, or whatever. I didn't realize it at the time, but my own therapy initially moved pretty quickly. We did the bulk of our trauma work within the first 12 sessions. My T later told me my progress had been "meteoric." Sure it was faster than some clients, but it was very much right for me. I hope you can look inside yourself and find the pace that is right for you. If you are going too fast, you can always slow down. Only you know. Good topic also for discussion with T, who may be able to reassure you or tease out from you info that will help guide the optimal pace.
