I have only scanned this thread so apologies if I have misunderstood anything or if I'm just repeating what others have said. But a few things caught my eye that I wanted to comment on.
Firstly, as I think some others have advised, if your everyday functioning is so poor and your anxiety and symptoms are so high off the scale, I would imagine that digging into and trying to process trauma (through EMDR or any other method) is not going to be helpful right now.
I haven't tried EMDR but have still dissociated a lot in therapy. And a fair amount outside of therapy! I've been in therapy for almost three years now and the last six months I haven't dissociated. This is progress! But it felt like forever getting to that point and I don't know that it's been gone forever - and I have no idea really what changed to get to that point! It has just taken time. And I have done plenty of sessions where the purpose of the session was simply (!) for me to keep my head in the room and stay in relationship with my therapist. It felt very tedious and frustration when I was so keen to push on and make progress. But you really can't force this stuff.
it was when I started mindfully brushing my teeth 'I am doing this because I am taking care of my body' that really seemed to have me turn the corner and start thinking in terms of my body and what it needed.
Body awareness has always freaked me out too. Like you, even if my therapist wanted me to say what I felt in my big toe, my head was totally gone in an instant. A bit like
@shimmerz though, I think my breakthrough (though that sounds profound and dramatic, which wasn't the way it happened!) was when I had a surgery earlier this year. I had to do a lot of physio afterwards. I've had to go to the gym. Very challenging and I struggled a lot with these things that required me to connect to my body. In the end though, it did come down to me thinking, hang on, after 15 years of chronic pain, I've finally ended up with a surgeon who's confident he can help and I've had this surgery and now it's on me to do the rest. And if I can't or won't do the rest of the work that needs to be done, I won't get as good a result. And after all this time, stress and pain, I want to really try to ensure that I get the best outcome I can. So, I kept going, I kept trying, I kept showing up for appointments and sessions, I kept doing what I could (which sometimes was only a couple of minutes) and I kept focused on the outcome I wanted. It wasn't easy. But that realisation/reframing really did help and now I am in a better position with body stuff than I was (I'm by no means great with it now - far from it - but there is an improvement, which I can keep trying to build on)
The split extreme thinking is a symptom of the feelings never the cause, the thing that has to change is my emotions first. I truly don't believe anyone has changed thinking first then as a result had their feelings calm
Not sure I agree with this. And it's not really about this:
there's no way I could willpower my way out of this kind of stressful thought.
It's perhaps more about reframing or focusing on what's really important/an outcome or something. A bit like I did with the choice I made about my post-surgery stuff. I don't think anyone is suggesting you can just use will power to think differently about something.
And re mindfulness - I agree with others that it can be an active thing not simply a passive, clear your mind meditation type thing. If the body stuff is freaking you out right now, can you try being mindful with something that doesn't need a huge connection to your body and physicality. For instance, colouring in? The mindfulness is more on putting your focus on choosing your colours and keeping neatly within the lines and seeing your picture emerging etc rather than "how does this pen feel in my hand?" It's one that has worked for me, anyway.
Also, I agree with whoever said about getting into a routine of breathing exercises morning and night as it's great for stimulating the para sympathetic nervous system. I know they are not for everyone as I have seen people post here before that they send them into a panic. The only reason I mentioned it here really was to say that, again, it doesn't have to be a clear your mind activity, which sometimes people really struggle with. When I do mine, I somehow sort of split my mind. Not sure if it is healthy or not, but it works for me! Part of me counts but I don't put a lot of conscious effort/focus there - it's like the counting is sort of happening in the background on auto pilot but it's keeping me on track and in a good rhythm. The main part of my brain is just thinking. Not stressful thoughts and not thinking about my body or my breath. Just thinking about the day...something that I did at work, a conversation I had, something I've just watched on TV.
Don't know if any of that helps?
You do sound a bit resigned to the fact that nothing works, nothing will work and you're beyond help? I don't think any of us are beyond help.
