Hey Elin, I'm not sure if you are a man or women, so I am not sure the exacts of the situation, but I don't think that matters all that much. I am in a similar situation with a past professor of mine. Completely obsessed, constantly thinking about her, and everything so believe me, I know how it feels. As for advice... well, I wish I knew, because I am trying to get over my crush as well. All I know is that eventually time will make her fade away. Reality of it is, that could take a year or more. Usually with me, it takes a good year to completely get over someone I really had feelings for. What is the situation with this person? Is this high school or college? Have you actually asked them out for coffee or something? It may or may not be appropriate. As for me, well mine was a failed attempt. I emailed the professor asking if I could stop by her office to say hello before I graduated, and she just ignored the email. So that's that. I suppose the best piece of advice really is to just stop putting them on a pedestal. They are not as great as you think they are. I mean my professor just ignored a request of a student to visit them? Kinda cold don'tcha think? Anyway it might be best to just realize it wasn't meant to be. It is a hard reality that I am slowly coming to terms with. In the end you will realize all the waiting and dreaming just isn't worth it. This might also sound corny, but this might also be an excellent opportunity to build yourself. There must be something lacking in your life to make you feel you need this person. At least that was the case with me. I admired her intellect. And now realize that I can myself become what I saw in her by taking my education more seriously. Sorry if none of this really makes sense. I myself am still trying to get over my crush, which I know will take a while. And on top of that coming to terms with the fact that I probably came off as a huge creep to her anyway for sending that email.
