Hi AnnaL and warm welcome to our community
I am so pleased you've found your way here. My heart goes out to you as you take such inspiring steps to help yourself move forward in your life. It's terrible to hear that the outcome to your saying something about your childhood abuse unravelled negative and seriously stressful outcomes. You're safe here and will find people very supportive and caring.
PTSD, anxiety and depression can have some very debilitating physical symptoms that I can relate to as I was abused as a child. I understand how you must feel having a twitch and facial spasm. While I haven't had your type of symptoms, mine are more around - stomach upsets, fatigue, muscular pain. It took me years to find out that it was associated with my mental health as opposed to any physical illness.
While I haven't used EDMR and neurofeedback, I have used similar types of treatment, i.e. EFT and trauma focussed cognitive behaviour therapy. These therapies helped me tremendously to help shift my neuropathways that had been damaged through trauma to new neuropathways. I can't explain the difference it's made in my life. There are times when I still have stomach upsets, fatigue and muscular pain - it's so much easier for me now to recognise what's happening and where it's come from.
So I imagine that EDMR and neurofeedback ought have a positive outcome for you. One thing I'd like to let you know (which is probably painful, but I need to let you know) - sometimes you may feel worse, e.g. the twitch may increase for a little while. This occurs I think because all the trauma is being brought to the surface and it's almost like reliving the trauma. I found talking to my psychologist about other options to help me deal with what is coming to the surface, e.g. mindfulness, reiki, acupuncture. I found these to be very effective to help sooth my very sensitive skin and nerves. The journey takes time, and patience.
From what you've written I believe you have the resilience to take the journey, to recover and to heal. Remember our forums are here for you.
