How do they get assigned to a counselor? At my school if you asked for a teacher change based on this it likely would honored as it’s based on your family’s personal experience, not what you’ve heard. But our school also does counselors for the entire grade (they loop with the kids so they have the chance over multiple years to get to know them) so it really wouldn’t be possible to request a different counselor. If it’s just the kids are randomly assigned I’d absolutely request a change as it sounds like you’ll have a hard time working with her. I wouldn’t put anything too specific in email, just that you’d like someone different as PP suggested.
