I'm talking about obsession over a person that you don't really know that well . . . it starts with infatuation, then jealousy, the you are thinking of this person all the time and they are the centre of the universe and if you are not near them then you might as well be living underground in Iceland cos nothing you do matters if this person doesn't see it.

I am feeling this way now and if anybody can explain this particular problem, I would be most grateful . . .

Thanks.
