"So I thought maybe his techniques can help me"

I have been sick for the past 5 1/2 years, have various symptoms but no Doctor has been able to diagnose anything. One of the main symptoms is severe shortness of breath which has affected my brain a lot. I can’t focus, can’t remember conversations, I start reading a book and by the time I am on my 3rd page I forget what I have read on previous pages. I have brain fog. I have seen specialists done endless of tests from brain MRIs, neurological tests, muscle biopsies and still no diagnosis. I attended the masterclass for Superbrain with Jim Kwik, and he talked about a lot of the symptoms I have. So I thought maybe his techniques can help me.
