Am i obssesed with her?

Ok so im a girl, im 14. I have this teacher that i adore, shes so nice and caring and i dlove her to be my mother! Im not very close to my mother you see. This teacher is really nice to me. She sort of stalks me if im being honest.. Read one of my othe questions if you want to know how. But im like obsessed with her now! Its like i want to be around her because i want to know what shes really like. And because i have a feeling she sort of stalks me and that... i do things that tests her.. if you dont understand. Eg. I walk home often to see if she watches me when she drives past. SHe even makes me sit close to her desk in her class and she lets me get away with anything lol. I want to even take this subject as a GCSE option because of her! she's amazing. But does anyone think they know why i want her to adopt me and that:/? I think im being stupid and that i should try to ignore her but its hard! advice please?xx
