Should I trust her?

My suggestion, logically reveal the counselor's intent. Instead of then asking you questions, pose a couple of your own: Why are you here? What do you hope to accomplish by talking to me? Why should I be scrutinized for my beliefs? Do you have anything better to do? (Mind you, the last two may come off as rude, best to avoid them.) Take a NotePad with you, right down responses and try to Sherlock Holmes it.

Another logical idea is to educate your councilor, if they learn more about your beliefs, they may not label you again. Compare it to Christianity or Catholicism, so that they realize that it's a religion as well as belief system. (And if you live in a town that isn't witch friendly, try not to practice in front of people... For your own safety.)

my situations a bit like yours , in school people call me names , they all think I'm insane,unusuall,creepy(the list goes on)
the thing is you have to stay strong in what you belive in. dot let others change your mind about things.
I told my perents..we argued about it ll the time, we still do but I just engnore all the things thay say because I KNOW what I belive in and NOTHING thay say will ever change that .
if you like you can mail me and we can shere experiences.
I hope things will get better for you.

To be honest i think i am the only Wiccan in my state...

My parents dont even know i practice it... But they do buy me candles because i say i want to smell them...
