I guess I don't really understand what people mean when they say "trauma work".
For me, those are the processing sessions; I use EFT, so its the tapping work. For an EMDR person, it would be the actual doing the eye stuff. SE, I think it would be doing the bodywork. In other words, a session that is planned around doing the working through and processing the events of/story of the trauma. Not time spent on how those events affect everyday life, or what happened at work, or such.
For me, it even means no mucking around with being afraid to get into things. I'll get stuck, for sure; but if its a day when we are going to be doing trauma work, I really have incentive to break through those barriers; even if that means we only get through a few individual moments in the "story".
The follow-up session is then to deal with how hard the aftermath of that is in my daily life. Like with EMDR, I'm usually "off" for 24-48 hours following a processing session. More triggerable, increased hypervigilance, sleep issues - all the symptoms dial themselves up. So, we talk about that, how I'm coping (or not), how I still need to accept that this is tough stuff and I'm not supposed to be superwoman when it comes to healing, etc.
Within a 2 hour EFT (trauma work) session, we will generally take about 10 minutes to get focused on the task at hand, about 90 minutes actually
on the trauma (whatever section we are working on), and then the other 15-20 wrapping up and getting me back into a place where I can safely leave without being too dissociated or amped up.
