Thanks for your advice. I am waiting to hear back from two people at Myndlift, and I will see what we can do. Hopefully my local practitioner will help out with supplying any data they require. I remember the gist of my results but I don't actually have the scans myself.
I have been lucky enough to get funding for the local treatment, but at best (even if the practitioner doesn't make it impossible for me to continue) it will probably end at the end of the year. I like being able to put in extra effort myself, so hopefully I will get that sorted with Myndlift and take some control back. But I am still thinking I might give a neurofeedback brain camp/retreat/intensive program a go, probably next year. I can afford it, but I don't have money to burn and I only want to do it if it is worthwhile.
The problem I have had with the local therapist is that he doesn't listen when I talk and he only skim-reads emails - he responds to them as if he has read them and understood them, but when I next talk to him assuming he knows what I have told him I find he has understood nothing. I have been trying to explain the same things to him for several weeks, both in person and in email, and he seems to listen but then goes back to saying exactly the same things he was saying before, even though I had told him he had completely misunderstood everything and that I was finding it very frustrating. He wouldn't even just let that particular subject drop and not talk about it at all - he kept being the one to bring it up but getting everything completely wrong, until I got pretty direct with him (by email) about it. I was polite for weeks, but I felt it had gone beyond the point where it was actually right for me to be polite.
At my last session I said to him 'if you stress me again I will walk out', and he gave me a very cold look and said 'you are very welcome to walk out' - but I really want to try neurofeedback, so I stayed, but it obviously isn't very conducive to it working.
