Aw, don't feel bad. Your appendix is actually useful!
No but seriously, you used your left brain to compose your message, so it's actually working for you.
I think since your right brain is so dominant, looking away will make it harder to swtich. Cover everything except below her knees, and repeat "behind.... in front...." contrary to what you first see, until you actually see it that way.
So just before the leg sticking out goes
to the left side of the page, say
"behind" and imagine it as behind but coming around to the front, and then say
"in front" as the leg moves from the left side of the page
to the right side.
Say that to yourself and watch it for as long as it takes until you actually
see it that way, then remove your hand
without breaking your gaze and watch the rest of her spin counter-clockwise.
You can do it!
