I'm so sorry you are going through this--all of it. I appreciate the sharing though, and your tone of How-it-is! The ring-trick doc sounds amazing :)
Lots of prayers for you!! I too am a leftie, and when I taught creative writing classes, we'd always do a count, and ALWAYS a high number. Creatives. I do strange bits and piece right-handed--using a baseball bat, golf club, scissors with RH. (Made a difference when I was a hairdresser! And confused the school gym teacher!) I pitched and figure-skated left, though... no rhyme or reason to us!
