Well...
I'm glad to say that this infatuation is finally over, I think. I had what could be called an epiphany; that it's better to finally give up my hopes that have quite blatantly been in vain, and to move on with the rest of my life. Ultimately, it was self-destructive, and I'm glad to get it over with.
In regards to the girl who was the center of this, I'm glad to be able to see her as a friend. Perhaps counter-intuitively, it would seem that now I am no longer emotionally involved (it's quite amusing to consider that she has no knowledge of this), I can open up to her more.
Ah well. Hopefully, from now on I should be feeling a lot better. Huzzah!
