I understand. I do this too, with teachers. I used to be worse. I guess I've just learned that those feelings can be expressed in other ways, on my own (through my own private world, my poetry, my journal), that I should look at the way others gain approval from that teacher and mirror what they do instead of losing my cool and getting scarily obsessed. I used to stalk teachers sometimes.. I don't do that anymore. People are still on pedestals but I can keep my behavior in check.

I wouldn't tell her if I were you. Maybe.. notice your feelings of attachment to her. When you feel yourself needing her, what does it feel like in your body? Can you take a few moments with that feeling before you act on it? Maybe take five deep breaths while you just try to locate the feeling in your body when you feel the need to be with her, or when she doesn't give you the answer you want, and see if you can choose the right way to act after you take a short time-out.

Hope this helps. I know, it's not easy.
