I am in LOVE with Applejack, what should I do?

I have been in love with Applejack for 10 years to the point where females usually avoid me. I bring my Applejack body pillow to school and if anybody ever say something bad about her I go into a panic attack! I love her so much to the point it hurts and if anyone takes her from me I'll go insane. I love her platonically and I want to marry her!
