Literary Lark,
Hugs hugs hugs. I do find you lovable in so many ways! Unfortunately, love can't be forced. We find it when we least expect it and if it becomes too painful (because we love them more than they love us), we might have to distance ourselves or take a long break from the person causing pain. Obsession can make us lose perspective. Fantasies in our head aren't real. If our fantasies start becoming painful then that is a signal that we need to disengage and stop them. I realize that sometimes this is hard to do but in the case of the professor, when you are done with school--that obsession will fade when classes end so long as you don't "feed it". Try to use that great imagination of yours for something else? I know this is easier to say than do. I am sorry you are in so much pain. Unrequited love is painful. Find some distractions? More hugs to you.
