Adult causing unnecessary problems in my life. . . what can i do?

Definitely switch counselors if she's being a smug-faced twatt like that. They're there to help you, not put you down and ignore you. Especially if she's telling your parents things that aren't true and misconstruing your words - that's not right and that's not what they're there for. I'd switch, and she should be upset with herself for acting that way.
