I thought I'd come back to this thread, because I think I've found some answers to the questions I was asking almost a year ago. Also, because there are others who seem to be having difficulty with the NHS.
As I mentioned in the first post, I went to my GP in September 2011, she refferred me to the MH team for assessment.
In some ways it is my fault for not revealing a long list of trauma at the initial assessment. But, during the assessment he asked me about my symptoms at that time, not about my history. So I only spoke about symptoms from one trauma.
So I was referred to a tier 1 therapist. She is experienced in CBT and trauma focussed CBT. And she is strictly limited to no more than 20 sessions. The first 3/4 of those sessions are used for further assessment, for her to get to know further details of the person and to build trust.
In the next couple of sessions my dissociation became apparent. When we did re-living, childhood stuff became apparent. Then she was off sick and I coped by dissociating and seperating. So by the time she got back, there were 12 sessions left, and she felt my trauma was too complex to be treated in that time, and the risk of destabilisation was too high.
what happens in the UK if the therapy youre offered isnt effective? and...do you get offered a limited number of sessions and then get told to get on with it? or are you assessed again at the end of the initial treatment?
So in answer to these questions: yes, there are a limited number of sessions. You are re-assessed at regular intervals to see if the treatment is having an effect. But, if the therapist is not able to treat you in that time, it is probelematic.
I was given a choice to be referred to tier 2 MH. There I would be re-assessed in light of my additional needs (dissociation etc). Then, I would be prioritised - or as I'm not a danger to myself or anyone else, I would be de-prioritised. And I could expect the wait to be at least 12 months. Then there is no guarantee that therapy wouldn't be limited (as currently NHS is trying to cut services).
Thankfully, my therapist was helpful as she personally gathered details of other options (charities) that might suit me. So I've chosen this way.
The other thing that is worth mentioning, is that if I had some therapy, but then felt it necessary, I could go back to my GP and be referred again for a full 20 sessions at tier 1. If this was the case, my therapist would still have my notes, and we could get into therapy in session 1.
