“It was like you were running the story of my life. My thanks go to the brave emotional lady who explained how her unresolved symptoms over the years cost her her relationships that she went through while you were with her. My goodness, I have been there too with the same thing happening. Yes, only now am I clawing back energy and periods of good health mentally and physically.
