Sorry to hear that.
I also need to warn about Neurofeedback and bad professionals.
I was trained in a place called Neurocenter in Barcelona. I didn't new I had ME. I went for the ADHD, depression, chronic pain, brain fog, etc. My Brain Map showed I had a metabolic illness or some health problem. They put me on a SRM protocol even thought my SMR was ok. It gave me severe side effects. I felt aggressive even thought I am never like that. I was irritated, my pain was worst than ever, I even had suicidal thoughts. I found a paper that says that SMR can give side effects

The Center didn't paid much attention to it when I told them, just told me it was normal to get worst before getting better and that it was my "trauma leaving my body". One day I even left the place with a fever and other I started having rashes all over my face. They offered me to book sessions with other professionals in the Center to solve it. And even offered me psylocibin therapy, which is illegal in Spain. I spend 1800 euros in just getting worst.
One month after I developed ME at 100%. I started having several crashes, couldn't be awake all day, started to need stimulants to wake me up, etc. Then I was so bad I realized I had Me.
Neurofeedback left me severally deregulated. I am really sensitive and I suffer from side effects of more things and sadly Neurofeedback is full of scammers and unprofessionals just wanting to make money. Ive found out that the people training me were not even trained at NF or one was not even a Psychologist.
If you do Neurofeedback, please be really careful and research really well. Work with someone that understand what ME is and that is aware that we are really sensitive patients.
