Hi harrietta,
Welcome to the Forum and Wiki. It seems that you know this approach to healing, and that you're looking for support. I am sorry about your experience, both the stress, and symptoms. This is a hard time for many!
You have listed evidence that you may have TMS, including "doctors can't find anything" with the uti, and "sciatica diagnosis," sciatica being a common TMS symptom.
Also you're connecting these symptoms with your recent losses and the stress of business pressure.
So you're already well on your way. We have a couple of programs for free that I'd recommend you use, starting with the Structured Education Program, which is free.
I have great hope that you're deepening your "Sarno" work, and that you'll see great improvement.
Recommend:
Reading success stories, once per day.
Ignore "why am I not getting better?" type posts. They are valid, but will not help you deepen your trust, sense of reassurance, which is part of what is needed.
Find ways to "self soothe" which means pleasure, joy, satisfaction in any way you can. You want to increase neutral or positive experiences. TMS keeps you focussed on symptoms, fear about future, need to "fix" symptoms. Counteract this tendency gently when it arises.
Post questions and progress along the way! Be patient. Trust.
Andy
