Strange Infatuations?

[Deviant Fish]

I have an odd infatuation with someone whom i think of every single day, every hour of every day since i was a little girl (i'm 19 now), and the complicated thing is that he's not real, its allll in my head. I don't hear voices or anything, i'm not crazy, i'm just obsessed with this very clear idea of someone who i haven't met and i'm not sure what that means. its like having a fantasy man, but its more then a little fantasy, its in my head all the time, even when i have a bf whom i adore, i still think of this guy. i've gotten a little used to it, when i was a kid i didn't think anything of it, he was just sorta there, and now its like this infatuation is getting worse and i think about him more and more, and i write about him and i can't get him out of my head, i crave him as if i was in love, but he's not real!

does this sound familiar? does anyone have any advice on how i should handle this? because its starting to make me spiral. any advice, or reassurance, or even just knowing that i'm not the only person who goes through this would be nice

thanks
