Er ástin ekki öll þar sem hún er séð?

Elated? Depressed? Obsessed? You may be suffering lovesickness

Falling in love used to be fun. Now doctors are warning that the throes of passion should be seen as a potentially fatal medical disorder.

Psychologists say that "lovesickness" is a genuine disease that needs more awareness and diagnosis.

And those little actions that are normally seen as symptoms of the first flush of love - buying presents, waiting by the phone for a call or making a bit of an effort before a date - may actually be signs of deep-rooted problems to come.
