Day 19 and a step back

If anyone has the inclination to reassure me or throw some light on this, I would be very grateful - my TMS is restless legs syndrome (RLS) and which has gradually been improving to the point that for the last few nights I havent needed any therapies at all, which is so wonderful I can scarcely believe it. Then we went way for the weekend - I went to bed optimistic that the progress would be maintained, but the RLS came back. No matter what I tried regarding the "Sarno-talk" to my legs and brain, nothing worked and I had a hellish night, so the second night away I took some pills which did the job and I slept, but I was very worried about the back-slide. Once back home, it has been ok again. Am I just not far enough on the healing path such that when in perhaps a stressful environment my brain take over again? and no matter how much I try, I cant get control back. What am I not doing right? - yes, my default is that it is my fault!!!
