Thank you all for your quick responses! I do agree that EMDR is a treatment that many people respond to, and I have been fortunate to know a few.
I am going to take on board pieces of what each of you have said, because it makes sense to me.
My therapist didn't pre-screen me for EMDR treatment in the sense they didn't ask me about my respnses to the truama. Also, my therapist questions my psychosis,although 2 seperate consultants who have altogether been treating me for over 10 years, have diagnosed me with it. And I've had a number of psychotic episodes which have all led to my admission to hospital. But my T doesn't want to talk about that!!
My T won't aknowledge I have anything but PTSD, and yet my consultant is a phonecall away who will confirm the extent of my troubles.
I think I will have some questions for them when I next see them!

Thanks again for your posts, as I was feeling a bit lost in the sense of having no one to
talk to about this problem, and my family are pulling in one direction, my heart and mind is pulling in another...(!)
