SGB, can you SEE me now??!!!
CP, although it's part of your delusive condition to believe nobody has ever felt this way - we have. You are getting sympathy here ... but not indulgence! It passes. Really, it does.
Also, it's now been proven, with brain scans & all, that the state of In Love is indistinguishable from many mental illnesses (quite severe ones, at that). This forum is highly sympathetic to posters with mental illness - as it is to you.
The difference between say, schizophrenia and your limerence is that you don't require treatment with hefty pharmaceuticals. You can just decide to get over it, by following all the advice on the last two pages.
It'll hurt, but not for long. A person renouncing limerence should always get a new hairstyle, rapidly followed by several new outfits and a New Hobby.
Good luck!
