Toughbird-- Maybe this kind of thing is more common than people admit. Believe me, you are not alone in experiencing this. IMO you don't necessarily need therapy for it because talking about it can just make it worse. I think it is best not to feed the beast by focussing on other things (though I know it is hard to do but I think you can find something else in your life to focus on). For me, psych drugs work better than talk for easing my obsessive compulsiveness. Mine is OCD thoughts. The best thing for me about experiencing limerence is that it kills my appetite. Usually, I eat way too much. There is a silver lining in every life experience if you look hard enough.
