I have a crush on my teacher despite her being a dick to everyone I like
What makes you have a crush on someone who is a dick to everyone that you like?
I'm seeing her as a woman, not as an object.
Having a crush on your teacher may get in the way of your studies. Understand that it is highly unlikely for you to ever get the chance to have a relationship with a teacher.
I'm taking it as a compliment.
Your teacher runs the risk of loosing their job if you form a relationship with them. Think of it as protecting someone you care about.
