Who is your bumper rail?

I am the bowling ball picking up speed. Misguided. Spinning. Curled up, heading towards a gutter, a crash.
Helen is the steady hand, the guiding rail. She redirects and corrects my course. Even when I am at my lowest, I am reminded of the support.
Who do you turn to when things begin to spin? How do you help others stick to the course and nudge them forwards?
